Suivre les instructions du fabricant pour installer l’appareil et utiliser les accessoires recommandés par le fabricant.

Il convient de ne pas placer sur l’appareil de sources de flammes nues, telles que des bougies allumées.

L’appeil ne doit pas être exposé à des égouttements d’eau ou des éclaboussures et qu’aucun objet rempli de liquide tel que des vases ne doit être placé sur l’appareil.

Assurez que lappareil est fourni de la propre ventilation. Ne procédez pas à l’installation près de source de chaleur tels que radiateurs, registre de chaleur, fours ou autres appareils (incluant les amplificateurs) qui produisent de la chaleur.

Les dispositifs marqués d’une symbole “d’éclair” sont des parties dangereuses au toucher et que les câblages extérieurs connectés à ces dispositifs de connection extérieure doivent être effectivés par un opérateur formé ou en utilisant des cordons déjà préparés.

Cordon d’AlimentationNe pas enlever le dispositif de sécurité sur la prise polarisée ou la prise avec tige de mise à la masse du cordon d’alimentation. Une prise polarisée dispose de deux lames dont une plus large que l’autre. Une prise avec tige de mise à la masse dispose de deux lames en plus d’une troisième tige qui connecte à la masse. La lame plus large ou la tige de mise à la masse est prévu pour votre sécurité. La prise murale est désuète si elle n’est pas conçue pour accepter ce type de prise avec dispositif de sécurité. Dans ce cas, contactez un électricien pour faire remplacer la prise murale. Évitez d’endommager le cordon d’alimentation. N’UTILISEZ PAS L’APPAREIL si le cordon d’alimentation est endommagé.

MM11112299 ““TTHHEE IINNPPUUTT BBOOAARRDD””The input board processes the audio signal from the input jacks to the volume controlboard, (M1128).

Each channel consists of a balanced gain stage, switchable subsonic filter, and astereo / mono / bridge switch.

Looking at the left channel, the balanced input, (XLR Jack) and unbalanced input(phone jack) are wired in parallel to the input of a balanced operational amplifier, (U4).The gain of this stage is 0.82 (-1.3dB) balanced and 1.6 (4.0dB) unbalanced. ResistorsR25, R27 along with capacitors C11 and C12 form a radio interference elimination filter.

Switch S1 selects the cutoff frequency of the hi-pass subsonic filter. The subsonicfilter provides a 20Hz or 40 Hz high pass filter. The filter consists of a tee network onthe input of U3 along with R10, R28, C29 and C30, C33 and C34. The gain is 1 (0dB)in the passband, (above 100Hz).

The audio signals from the input board M1129 pass through the 14 conductor cableto board M1128.

MM11112288 ““VVOOLLUUMMEE CCOONNTTRROOLL BBOOAARRDD””This board contains:

• the front panel audio gain controls• the front panel indicating LED’s (power, protect, activity and clip).• the audio limiters

Circuit Explanation:• The left channel of the circuit is explained.(Refer to the schematic of M1128 as the sections of the circuit are explained.)

The audio signal out of M1129 passes through volume control P2 and the desiredlevel enters U2 through pin 6. U2 is set for a gain of 5 (14dB) when the volume controlis in the fully clockwise position.

The AP4020’s defeatable limiter is built around LD8. LD8 is an opto-resistive cellcomprising of an LED that shines on a photocell. As the LED in the LD8 becomesbrighter, the resistance of the photocell decreases, placing more of the audio signal onpin 5 (non-inverting input) of U2. This audio voltage gets subtracted from the signal onthe inverting input and less signal appears on the output of U2. Transistors Q5 and Q6along with the surrounding passive parts provide the attack and release time constantsof the limiting function along with the drive currents for the clip LED and the LEDinside LD8. When an audio signal on the output of the power amplifier section (onboard M1126) enters clipping, pulses representing the duration of the clipped portionappear at LCLIP. These pulses turn on transistor Q6, and Q6 provides current pulsesto turn on clip LED LD6. The pulses also pass through R7 and D6 to charge C3 andC36. When the voltage across C3 reaches 0.5 volts then Q5 turns on providing a cur-rent into the LED of the LD8 limiting the audio signal at U2. The charging (attack) anddischarging (release) times of the limiter are 80mS and 3.5 seconds respectively.Resistors R50 and R7 provide the charging path, and resistor R51 provides the dis-charge path. The limiter can be defeated by placing the limiter switch (S2) in the inposition which disconnects Q5 and the charging / discharging circuitry from V+.

The activity LED circuit consists of Q1 and the surrounding circuitry. The audio sig-nal enters the activity LED circuit through R2. R2 and C21 form a differentiator thatturns Q1 on illuminating the activity LED whenever the audio signal increases in ampli-tude. A constant current flows through R55A, R55B and when Q1 is off, the collectorcurrent then flows through D1.

From M1128 the audio signal passes through a 12-conductor ribbon cable to circuitboard M1127.

On M1127 an operational amplifier U201 re-references the ground for the audio sig-nal from LREF or RREF to the corresponding LOG (left output ground) or ROG (rightoutput ground). U201 also provides DC correction for DC offsets appearing on the out-put binding posts. Feedback from the output binding posts appears on LFNB or RFNB.Through R203A or R203B the DC offset achieves a gain of -1 from U201. The DC off-set of opposite polarity on the output of U201 will compensate for the DC offset in theamplifier section on M1146 resulting in 0 volts DC on the output binding posts.

• The audio signal continues to M1146 via an 8-conductor ribbon cable.

MM11112266 ““TTHHEE VVOOLLTTAAGGEE AAMMPPLLIIFFIIEERR AANNDDCCUURRRREENNTT AAMMPPLLIIFFIIEERR””This board contains:

• a voltage amplifier section• a current amplifier section• amplifier current limit section• DC output protection• heatsink temperature sensing

Voltage Amplifier SectionThe voltage amplifier amplifies the audio signal’s voltage from 8.1 volts peak (at theoutput of U201) to approximately 70v peak, which is required to drive the currentamplifier section. The current amplifier provides the current required for the 70v peaksignal to drive 1200 watts into 2 ohms out of the binding posts.

Before the circuit is described in detail here is a quick rundown on the signal’s paththrough the voltage amplifier stage. Refer to the schematic of M1126. Let’s considerthat a positive going AC signal is present at the SIG input. The positive going signalwill turn on the positive side of the voltage amplifier. The signal at the SIG input turnson Q12A (through R40A, D14A and D13A). The collector of Q12A pulls down on thebase of Q14A turns this transistor on further and allows a greater current to flow out ofQ14A’s collector. This increase in current passes through Q15A and it’s collector toemitter voltage decreases. The collector of Q15A now being more positive in voltageturns the base of Q18A on causing an increase in Q18A’s collector current resulting intest point 1 going positive.

As the positive side of the amplifier was turning on the negative side would havebeen turning off. This is how test point 1 was able to move positive following the inputsignal. The reverse would hold true if a negative going signal were present on the inputof the voltage amplifier.

CIRCUIT DESCRIPTION:The voltage amplifier is a mirrored image with circuitry connected to the positive powersupply rail being identical (but opposite polarity) to the circuitry connected to the nega-tive power supply rail.

For this reason we will look in detail at the positive side of the amplifier.

The audio signal enters the voltage amplifier at the SIG input. The signal passesthrough R40A, D14A and D13A to the base of Q12A. Diodes D13A and D14A set upthe DC bias on Q12A to approximately 0.6 mA.The first voltage gain stage consists of Q12A along with the resistor chain on its col-lector and the emitter resistor (R44A).

Transistor Q12A drives the base of Q14A through the resistor chain. A DC current ofapproximately 6 mA should flow through the collector of Q14A. The voltage dropacross Q14A remains constant and is derived from the voltage drop across the voltagereference Q20A, resistor R58A, and the base/emitter junction of Q15A. This total volt-age should equal approximately 3 VDC. Transistor Q14A is the second gain stage andits output current flows through Q15A. Transistor Q15A is a common base stage withthe collector driving the base of output buffer Q18A.

Diode D17A is a clamping diode that prevents the maximum peak of the audio sig-nal from coming within 4V of the 100 VDC rail. This is to prevent the output currentamplifier from going into saturation during clipping and therefore having storage delayproblems.

Transistor Q18A buffers the high impedance present on the collector of Q15A. Theoutput of the buffer provides a low output impedance at the junction of R61A andR62A and is current limited to 23mA through the clamping action of D19A, D20A andD23A. The signal at the junction of R61A and R62A drives the succeeding currentamplifier.

Current Amplifier SectionThe current amplifier receives a high voltage audio signal from the voltage amplifierand provides the current drive necessary to drive speaker cabinets.

The current amplifier is a two-tier complimentary output driver design controlled by acomplimentary darlington stage.

QUIESCENT CONDITION:This design is class A/B and therefore the output driver transistors must be forwardbiased to provide low crossover distortion. In most class A/B designs, a diode chain orVBE multiplier is used to control the bias voltage and provide a means of adjusting thebias. This design is different, as there isn’t a diode chain or VBE multiplier. For simplici-ty lets consider only the positive side of the current amplifier, that is all parts betweenthe positive power supply rails and the audio signal output/input terminals. The nega-tive side is the same as the positive, except for polarity changes.

To bias Q14, greater than 0.5V is needed from base to emitter, (or for simplicity frombase to amplifier output). Points A and B are at the same potential, so consider themto be connected. If this is true then 0.5V from test point 2 to the amplifier output mustappear across R12. There must be some way of developing this voltage across R12,and there is using the darington (Q5 and Q40) driver along with local feedback.

Simplified schematic #1 shows the biasing circuit. The current needed to develop 0.5Vacross R12 comes from the emitter of Q5. When the amplifier is first turned on the currentsource (Q3) turns on Q5 and Q40) and current flows through R12 developing a voltage.When this voltage approaches 0.5V Q1 turns on and robs current from the base of Q40.

This causes Q40 to turn off until the reduced current flowing through Q5 maintains0.5V across R12. Q1 will turn off slightly causing Q5 and Q40 to increase their collectorcurrents. The circuit reaches a point of equilibrium with approximately 0.5V across R12.

Because all output devices are not identical and base emitter voltages vary, someadjustment must be available to slightly adjust the 0.5V across R12. This is accom-plished with RT1. RT1 causes Q1 to turn on slightly more or less resulting in Q5 andQ40 turning on slightly more or less and therefore R12’ s voltage will be slightly moreor less than 0.5v. The proper quiescent current voltage is 4mV (to be measuredbetween test points 8 and 9).

The Second Tier and Tier Switc hingRefer to the simplified schematic Fig. #1 while reading the following text. One way ofmaking an amplifier more efficient is to vary the Power Supply Voltage on the collec-tors of the output transistors (Q14 & Q22). The lower the voltage from collector to emit-ter, the lower the device dissipation. During quiescent conditions, there is 55VDC onthe collectors of output transistors Q14 and Q22. The peak AC voltage that can appearon the amplifier’s output is approximately 95V peak. How can an output transistordeliver a 95V peak when its collector is only at 55VDC? It can if its collector is pulledup to 100VDC as the output signal’s peak rises above 55VDC. Refer to Fig. #2. Thesecond tier voltage must remain above the amplifier’s output voltage by amount Vm.Therefore the circuitry controlling the second tier voltage must increase the tier voltagebefore the amplifier’s output voltage reaches 55VDC. This leading voltage is necessaryto compensate for time lag of the second tier circuit during fast rising amplifier output

signals.

The voltage between the amplifier’s outputand test point 4 is approximately 12VDCderived from the voltage drop across ZD4. Wecall this voltage the “floating battery” because itfloats on top of the output audio signal with testpoint 4 always being 12VDC greater than thepeak of the output signal. Test point 4 drives thegate of mos-fet Q11. Q11 controls the transis-tors of the upper tier. As Q11 turns on its sourceforward biases the base of Q13 and Q13 pullsthe collector of Q14 towards the 100 volt rail.The gate to source voltage needed to turn onQ11 is approximately 3.5 volts. When the peakoutput signal is about 46.5vp (55v-(12v-3.5v))then Q11 will start to turn on the second tier.The second tier voltage will remain about 13volts (Vm) above the peak of the output signal

to the point of clipping where this voltage is reduced to about 6 volts (measured dri-ving an 8 ohm load). Zener ZD8 protects the gate source junction of Q11 and also pro-vides a supply current path through R29 for the “floating battery”.

NOTE: The Power supply voltages given are those when the amplifier is not driving aspeaker load. This will allow yo to check the tier switching with the cover of the amplifi-er off and the amplifier, therefore, running cool.

Current Limit Pr otection Cir cuitr yTo have an amplifier drive 3000 watts into practically any combination of speaker cabi-nets and know what is a safe load and what is not is a very difficult task. An extensive

amount of time was spent on the current limit circuitry so that it may simulate the safeoperating area of the output transistors (SOAR curve). No matter how reactive the loadmay be the phase shift that it presents, along with it’s resistive component is used toset the output current limit of the output transistor stage.Refer to the schematic of board M1126 while reading the following text. The currentlimit circuitry is a mirrored image with circuitry connected to the positive power supplyrail being identical (but opposite polarity) to the circuitry connected to the negativepower supply rail. For this reason we will look at the positive side of the circuitry.

Transistor Q9 measures the peak current flowing through resistor R53. The voltageacross R53 (as a result of the current flowing through it) is scaled down by R55, R35,R35A, R36, R37, D7 and D11 these parts make up the safe operating area along withthe time constants of C30, R34, C12 and R26. Fig. #3 shows a waveform of the currentthat passes through R52 and R53 when the output of the amplifier is shorted to ground.This can only be seen by using an oscilloscope to measure differentially across R52and R53. The conditions of the measurement are contained on the diagram. During cur-rent limit when Q9 turns on it reduces the voltage across R42. R42 is in series with a16 volt zener (ZD7) and is also in parallel with the junction of Q8. The current that flowsthrough R20, ZD7, R42, and R22 normally saturates Q8. When Q9 reduces the voltageacross ZD9 and R42 to below 16.6 volts, Q8 turns off allowing a charge to build up onC8 through resistors R24 and R25. If current limiting occurs for a long enough durationto allow C8 to charge to 1.2 volts then Q7 will turn on tripping the relay circuit on boardM1127. As soon as the relay is tripped the audio signal will be turned off at the outputof the voltage amplifiers and will remain off for about 5 seconds before the relay turnson and allows the audio signal to pass through the amplifier. If a current limit conditionis still present then the whole cycle will occur again and repeat until the load conditionson the amplifier’s output are safe for the amplifier. When a safe load appears the ampli-fier will automatically reset and drive that load (the speaker cabinet).

DC ProtectionIf a DC voltage greater than 8 volts appears on the output of the amplifier for morethan 200 milliseconds then triac Q30 will turn on holding the output at ground poten-tial. MBS4992 is a device that turns on at either + or - 8 volts DC.

NOTE: Every time you replace blown output transistors on a M1126 board test the DC protection triac with the following circuit.

Conditions of test:

A) Pass a 100Hz 25v peak signal through the M1126 board under test with no loadconnected to the amplifier output.

B) Connect points 1 and 2 as shown in the diagram. The amplifier should go into pro-tect mode as the triac (if working) shorted the output of the amplifier to ground, andthe amplifier goes into current limit.

C) Disconnect the triac test circuit and allow the amplifier to complete it’s protect cycle.

D) Reverse connections 1 to 2 and 2 to 1 and test again. The same results as in B)should be observed if the triac is working.

Only test the triac for one protect cycle asprolonged testing will heat the triac to a high temperature.

• The shutdown relay and its associated drive circuitry have two possibleoperating states.• Amplifier on under normal operating conditions.• Amplifier power switch has just been turned OFF/ON, or the amplifier is in currentlimit protecting the amplifier’s output transistors, or the amplifier has overheated.

Shutdown CircuitHere is how the circuit accomplishes these functions. The relay’s normally closed con-tacts short the output of the voltage amplifiers to ground when the power switch is off.When the power switch is turned on, the relay remains off (normally closed) for about6 seconds. C203 charges to 35V and results in Q203 turning off allowing Q201 to turnon. As Q201 turns on, it connects the negative terminal of the relay’s coil (Pin 16) toground energizing the relay and opening the normally closed contacts.



SERVICE MANUALYorkville Sound • http://www.yorkville.com

If prolonged current limiting occurs on the amplifier’s output transistors then D204 orD205 (depending on which channel is current limiting) will be forward biased turning onQ202 (from its off state). Now +100VDC appears on the collector of Q202 and throughR210 and R211 turn on Q203 therefore turning off Q201 by shorting its base emitterjunction. Q201 turning off will turn the relay off and the normally closed contacts (offstate) will short the outputs of the voltage amplifiers to ground so as not to continuouslystress the amplifier’s output transistors. A cycle now occurs. With the voltage amplifiersnow disabled there is no signal driving the output transistors (Q13 to Q28).

The current limit circuit protecting the output transistors (Q13 to Q28) turns off andD204 and/or D205 are not forward biased and Q202 turns off. Through Q203 andQ201 the relay is turned back on and the voltage amplifiers are now active again, dri-ving the output transistors. If current limiting still occurs, then the same cycle will occur.If the cause of current limiting (low impedance or short on the speaker output termi-nals) has been removed, then the amplifier will continue to operate normally.

The third operation that the relay provides is “overheat shutdown”. If for some rea-son the fan cannot keep the heatsinks in a safe operating temperature area then thefan control circuit (on board M1127) will deliver through D207 a positive current to turnQ203 on and turn Q201 off to turn off the relay and disable the voltage amplifiers.When the fan has cooled down the temperature of the amplifier, then the signalthrough D207 will disappear and the relay circuit will turn on the relay to resume nor-mal operation. Anytime the relay is in the “protect” mode (due to the abnormal states)then contact pin 4 of the relay will illuminate LD3 (the protect LED on the front panel).

Soft Turn On CircuitTo reduce the “inrush” current that flows through the line cord from the 120 VAC powersource (typical with large linear power supplies), a circuit provides a soft turn on func-tion. When the power switch is turned on, the current that initially flows through the pri-mary of the transformer must flow through SG201 and SG202. These are surgestorsthat reduce the peak inrush current flow. After about 500 milliseconds a relay’s con-tacts short across the surgestors so that they are not stressed by the current flowingthrough them under normal operation. A circuit consisting of Q240, Q241, C215, andthe associated resistors provides the time delay for the turn on cycle of the relay. Thecircuit is very similar to the shutdown time delay circuit. Refer to the section on theshutdown circuit for a circuit description.

Fan CircuitLooking at the schematic to board M1127, here is aquick explanation of the fan control circuit. There isa temperature sensor (AS35) on each M1126board. When the amplifier is first turned on, Q207and Q208 are off. The AS35 temperature sensorsare configured as temperature controlled currentsources. As either temperature sensor begins toheat up, more current flows through D212 or D218increasing the voltage drop across R235 or R236.The hotter temperature sensor will provide morecurrent than the cooler sensor and therefore devel-op a higher voltage across it’s associated 8K2resistor. The higher voltage will forward bias D212or D218 reverse biasing the cooler temperature

sensor’s diode so that the hotter sensor will control the fan speed. At 40 degrees C there

is 10 volts across R235 or R236 which is enough to turn on Q210, Q208, and Q207 pro-viding 7 DC volts to the fan. Further heating the temperature sensors results in a largerDC voltage across the fan. To lower the dissipation of Q207, D215, D216, ZD205, ZD206and R226 turn off Q207 and Q208 when the full wave rectified voltage present of the col-lector of Q207 reaches approximately 45V by robbing current from the base of Q208.The maximum fan voltage is 20.5 VDC. ZD207 and R228, R229 and R230 provide a cur-rent limiting function. Figure #4 shows the current through these resistors when there is12VDC across the fan.

Thermal Shutdown CircuitThe emitter of Q210 in the fan circuit is the measuring point for the shutdown voltage.As the temperature sensing devices (AS35) that control the fan circuit heat up the volt-age on the emitter of Q210 rises until at 85 degrees Celsius on the M1126 heatsinks.The voltage on the emitter of Q210 reaches 18 (85 degrees C) VDC and the amplifiermust be shutdown to protect the output power transistors. ZD202 and D207 becomeforward biased and Q203 turns on turning the relay off and muting the audio signal.After the amplifier cools down the voltage will decrease until Q37 turns off turning therelay back on enabling the amplifier.

IIddeennttiiffyyiinngg DDeeffeeccttiivvee BBooaarrddss iinn tthhee AAPP44002200STEP 1: VISUAL INSPECTION OF FRONT PANEL AND FAN

• Check to see whether the green power LED is lit. If not, the amplifier has apower supply (M1127 board), transformer, A.C. switch or line cord problem.• If the red protect LED stays on or samples off and on, this usually indicates aproblem with the voltage amplifier or current amplifier sections on one or both ofthe M1126 boards. Check for misaligned pin connections or see if the ribboncables have been cut or pinched through their insulation.• If the fan is running at full speed at power up this usually indicates a problemwith the fan circuitry on the M1127 board, but it can also be caused by M1126 cir-cuit problems. A damaged AS35 temperature sensor located under the M1126heatsinks can cause erratic fan behavior.• No output on either or both channels could be caused by intermittent pushswitches on the input board.

STEP 2: VISUAL INSPECTION OF INTERNAL CHASSIS AND INITIAL TESTINGAfter removing the lid, look for any signs of smoke, charring or burnt components.Before powering up replace the burnt components, and check the associated circuitryfor damaged parts. Disconnect one M1127 board and test one board at a time toreduce the possibility of further damage. Use a variac to slowly increase the 120 VACup from 0 volts while monitoring the quiescent current with a meter and the speakeroutput with an oscilloscope. Watch the speaker output for large DC offsets, or oscilla-tion. Watch the meter for large collector currents flowing. Remember under quiescentconditions, there should only be 3 to 5 millivolts across test points 8 and 9 on the out-put stage of the amplifier.

Quick Fix for M1146 & M1126To speed up the servicing of the AP4020 or AP4040 on your bench, YorkvilleSound’s service department has developed a method to replace the compo-nents most likely to fail when a M1146 amplifier board requires service.

This Quick Fix kit contains the procedure, assembly drawings, and compo-nents to perform the Quick Fix to a M1146 or M1126 board.

It should be understood that the person using this procedure knows how totest resistors, diodes, and transistors to determine if they are defective. This pro-cedure is not intended to be a substitute for one’s lack of electronic capability.

Before starting, look at the board for repair and locate the version number.It is very important that you follow the procedure for the appropriate circuitboard version number.

A complimentary service manual for the AP4020 power amplifier is sup-plied with this M1146KIT.

STEP 1. Locate the assembly drawing for the version number printedon the M1146 or M1126 circuit board to be serviced.

STEP 2. Remove all of the transistors coloured RED on the assem-bly drawing.

STEP 3. Measure and remove any of the diodes coloured BLUE on theassembly drawing that may be damaged. Replace a 1N4732A 1W4V7 zener (#6459) ZD12 along with a series 0.5 ohm R85 resistor.

STEP 4. Rotate the trim pot RT1 fully counter - clockwise as in figure 1.Inspect and replace any resistors that look burnt. Measure all ofthe resistor values coloured YELLOW on the assembly drawing.The value that you measure may not be exactly what is shownon the assembly drawing but if the resistor doesn’t look dam-aged it should measure within + or – 5% of the printed value.

STEP 6. Measure across the pair of test points shown in the componentlayout listed in the table below. If the measured value is notwithin + or – 10% of the value listed in the table then replacethe resistors shown in the table below.

STEP 7. Measure the resistors coloured ORANGE. Since the value ofthese resistors is 0.1 ohm, your ohmmeter will measure thehigher series resistance of the test leads if the resistor is OK. Ifthe resistor is damaged your ohmmeter will read a very highresistance (an open circuit). Replace any damaged resistors.

STEP 8. Measure the output TO–3 transistors (Q13 to Q28) to deter-mine if any are damaged. Mark any damaged transistors witha marking pen.

STEP 9. Replace any output transistors that you have marked as beingdamaged. Replace any diodes that you have found to be dam-aged. Replace all of the red transistors that were removed.

STEP 10. Inspect the traces on the circuit board for any that have ‘fused’open or looklike they got very hot. Bridge and solder a piece ofwire over any damaged traces.

Testing Repaired Circuit BoardsNow that you have rebuilt the M1146 or M1126 circuit board. It is just asimportant to properly power up the board. If the sinewave doesn’t look rightcheck the signal at test point (1) to ensure that the voltage amplifier isn’t dis-torting the signal. If there is still a damaged part on the board instantly turn-ing it on could blow up the board and you would be back where you started.

Connect the power wires and ground to the power supply. Connect a digi-tal multimeter to test pins 8 and 9 to measure the bias quiescent currentand place a scope probe on the speaker output. Be sure to turn the quies-cent current trimpot RT1 fully counter clockwise.

Now using a variac slowly turn up the AC main voltage while monitoringthe quiescent voltage and the speaker output trace on the scope. Watchingthese two test points is a good indicator of the health of the board. If youhave a second multimeter connect it up from the speaker output to testpoint 4 or 5. As you variac up also check these DC battery voltages toensure that they both increase in voltage to approximately +12 or –12 vdc.

If the board looks OK after variacing up to 120vac then slowly turn up thebias (RT1 trimpot) to obtain 3 to 5 millivolts of bias voltage on test points 8and 9. Check the speaker output with a 1KHZ sinewave with no load. If thislooks good place the minimum rated load (4 Ohm for M1126, 2 Ohm forM1146) on the speaker output and increase the sinewave amplitude to thepoint of clipping. If the signal looks free of oscillation, place a short acrossthe speaker posts. The amplifier should go into protect mode after 1/10 of asecond. Remove the short and the sinewave will appear 6 seconds later.

Reassemble the complete amplifier and run just clipping music or pinknoise into the minimum rated speaker load for that model of amplifier. Letthe amplifier heat up for 20 minutes. This will check the thermal mounting ofthe transistors and for any weak parts not caught during troubleshooting.
