Also set semi-fixed resistor R719 (R CH) and R720 (L CH) on the PC board (PS07) to the center positions. 2) Connect a digital multimet

22、er, set for the DC V range, across the pins on the two ends of cement resistor R737 (L CH) or R738 (R CH) on the PC board (PS07). 3) After the above, adjust the idling current as follows: Turn power ON, and adjust semi-fixed resistor R719 or R720 on the PC board (PS07) while observing the digital mu

23、ltimeter indication. The target value is 7 mV (19 mA). ReferenceWhen the power of a set after idling current adjustment is turned ON with the set in cold condition, the currents increase gradually as shown in the following table. If the idling current is adjusted in less than 5 minutes after turning

24、 power ON, adjust referring to the following table. Period after power ONIdling current values 30 sec. _ 1 min.4.0 mV 1 min. _ 2 min.5.0 mV 2 min. _ 3 min.6.0 mV 5 min. or more7.0 mV 4) If the adjustment is made after heat run, aging or servicing, leave the set with no signal, no load and power ON f

25、or 10 minutes, then adjust to the target value of 7 mV. 3.
