CURRENT ADJUSTMENT
1. Before switching the power ON, set the master volume control to the minimum
position and the balance volume to the center positions. Also set semi-fixed
resistors R755(L ch) and R756(R ch) on PCB P701 to the center positions.
2. Each of the cement resistors R767(L ch) and R768(Rch) on the PCB P701 is provided with three test points. Connect a digital voltmeter, set for the DC voltage input, to the test points at the two extremities of the three test points of R767 or R768.
3. After the setup above, switch the power ON, and adjust semi-fixed resistors R755(L ch) and R756(R ch) on PCB P701 according to the digital voltmeter reading. The target setting value is 10 mV(50 mA) for both the L ch and R ch.
