SAFETY INSTRUCTIONSGENERAL GUIDELINES

1. It is advised to insert an isolation transformer

in the AC supply before servicing a hot

chassis.

2. Potentials as high as 33KV are present when

this receiver is in operation. Operation of the

receiver without the rear cover involves the

danger of a shock hazard from the receiverpower supply. Servicing should not be

attempted by any one who is not

competent with the precautions necessarywhen working on the high voltageequipment. Always discharge the anode of

the tube.

3. When servicing observe the original leaddress in the high voltage circuits. If a short

circuit is found, replace all the parts which

have been overheated or damaged by the

short circuit.

4. Always use the manufac turers replacement

safety components. The critical safety

components marked with on the

schematics diagrams should not bereplaced by other substitutes. Other

substitute may create the electrical shock,

fire or other hazards Take attention to

connectors, control shafts etc. When the

exposed metallic part a return path to thechassis the reading should be between

4Mohm and the 20Mohm. When the

exposed metal does not have a return path

to the chassis, the reading must be infinite.

LEAKAGE CURRENT HOT CHECK

1. Plug the AC cord direc tly in to the ACoutlet. Do not use an isolation transformer

for this check.

2. Connect a 2Kohm 10W resistor in series withan exposed metallic part on the receiverand an earth, such as a water pipe.

3. Use an AC voltmeter with high impedance

to measure the potential across the resistor.

4. Check each exposed metallic part andcheck the voltage at the each point.

5. Reverse the AC plug at the outlet and

repeat each of the above measurements.

6. The potential at the any point should notexceed 1.4 Vrms. In case a measurement is

outside the limits specified, there is the

possibility of a shock hazard, and the

receiver should be repaired and rechecked

before it is returned to the customer.
