SERVICING

1. PULSE POWER SUPPLY BOARD REPAIRING
This set has a pulse power-supply circuit which
is quite different from a conventional power-
supply circuit. The pulse power supply directly
retifies and smooths the ac input power to pro-
duce the higher dc voltages required in the power
supply circuit, When servicing this set, note the
following.

a) To prevent unwanted radiation due to pulse
signals in the pulse power-supply circuit, the
pulse power-supply board is shielded by the
aluminum diccast box.

b) The negative circuit of the secondary rectifier
in the pulse powersupply circuit is grounded
by screws in the aluminum diecast box. When
checking the pulse powersupply board out
of the box, use a jumperwire and a cardboard
insulator as shown on the right.

2. Take care that electrolytic capacitor C414 which
is used after the rectification of ac power soure
voltage is charged even if the POWER switch is
turned off. Be sure to use a resistor of at least
several hundred ohms to discharge the capacitor,
Direct discharge by means of lead is dangerous.

3. INVERTER CIRCUIT TRANSISTOR REPLACEMENT (0903-906)

When replacing 0903-Q906 in the pulse power-
supply circuit, use those which have the same hFE
rank and color code.
