AMP ADJUSTMENT

Confirmation and Adjustment of Iding Current of Main Amplifier
Right after power is turned on, confirm that the voltage across the terminals of CB111,CB112 and CB113 is between 0.1mV~3.0mV.
If it exceeds 3.0mV, open (cut off) R120 (on CB111), R127 (on CB112) or R134 (on CB113) and reconfirm the voltage again.
