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.
