SERVICE POINT

- As this unit uses a large capacity power supply,
be careful of the following points when check-
ing and repairing.

(1) To check and repair the printed wiring boards, be
sure to cut off the power and pull out the power
cord. Remove the bottom plate and discharge the
power capacitors by touching it with a resistor of
approx. 10 ohms, 5 watts capacity at the positions
C807 and C808.

(2) This amplifier employs a heat Sink and so when
conducting a continuity check. the unit should be
placed horizontally or stood on its transformer
end.

0 Parts installation method
Great care is taken in installing parts to improve the
safety of products. For example, parts are covered
with tubes, or they are kept away from the printed
wiring board surface. Be sure to maintain the
previous conditions after replacing parts for repair.
