ALIGNMENTSIdling Current Adjustment (for PHONES power amp.)Set the power voltage to rated voltage for this adjustment.Adjust the Idling Current with the variable resistor RH87 and RH88 on the PWB (PH81).1. Turn off the power.2. Connect Digital Voltage to No. 1 to No.4 pin of JH83. (The connection is follows) No. 1 pin (Rch -) : Digital Voltage - No. 2 pin (Rch +) : Digital Voltage + No. 3 pin (Lch -) : Digital Voltage - No. 4 pin (Lch +) : Digital Voltage +3. Before turning on the power, RH87 and RH88 have been counter clockwise turned with the adjustment driver.4. Turn on the power.5. After turn on the power 3 minutes, With seeing the digital voltage meter turn the variable resister clockwise slowly to adjust the idling current. Idling adjustment with RH87 (RH88). Turn RH87 (RH88) clockwise to increase the idling current. The adjustment value of idling current is 10mV(10mA) 0.5mV(0.5mA) each.6. After turn on the power 5 minutes, repeat the Same procedure as 5. The adjustment value of idling current is 10mV(10mA) 0.5mV(0.5mA) each.7. Idling current decreases with the temperature rise inside the unit, and it is set to about 9mV (9mA) of setting value in about 30 minutes after turn on the power. Adjustment is completed.8.
