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.

– AMP BOARD (COMPONENT SIDE) –
Procedure :
1. Rotate the variable resistorsVR101, 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 +14.4V, 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.
