Connect a DC Millivoltmeter to L Channel speaker output terminals. 2. Turn unit “ON” and adjust VR101 (10

2、0ohms) to get a reading on IC107 Pin 1, which must be 100mV. 3. Connect the DC Millivoltmeter to R Channel speaker output terminals and adjust VR102 (100ohms) to get a reading on IC108 Pin 1, which must be 100mV. B. IDLING CURRENT 1. Leave power “ON” for a minimum of 5 minutes. 2. Connect a DC Milli
