Notes on Chip Component Replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

ELECTRICAL ADJUSTMENT
Bias Adjustment
Note : The Bias adjustment should be performed only if any of
Q106, Q107, Q206, Q207, Q306, Q307, Q406, Q407, Q506,
Q507, Q509 and Q510 are replaced.
Setting :
Stabilized
Power supply
B+,REM terminals
set
GND terminal test points
Procedure :
1. Rotate the variable resistors VR101, VR201, VR301, VR401
and VR501 fully in the clockwise direction to minimize the
idling current of the stabilized power supply.
2. The input signal is to be no signal.
3. Set the power voltage to +14.4 V, and turn the remote mode ON
(Connect between the REM terminal and B+ terminal).
4. Connect on digital voltmeter between each test points.
5. Adjust VR101, VR201, VR301 and VR401 so that the digital
voltmeter reading is 5 ± 0.5 mV.
6. Adjust VR501 so that the digital voltmeter reading is
3.5 ± 0.5 mV.
