Confirmation of Idling Current of MAIN (1) P. C. B.
Right after power is turned on, confirm that each
measured voltage across the terminals of R45 (Front
Lch), R46 (Front Rch), R50 (Center), R47 (Surround
Lch), R48 (Surround Rch), R49 (Surround Back) is
between 0.1mV and 10.0mV.
If it exceeds 10.0mV, open (cutoff) R38 (Front Lch),
R39 (Front Rch), R37 (Center), R34 (Surround Lch),
R35 (Surround Rch), R36 (Surround Back) and
reconfirm the voltage.
Attention
If the measured voltage exceeds 10.0mV after an
amplifier repair, first check for a defective component
before cutting the bias resistor.
Confirm that the voltage is 0.2mV ~ 15.0mV after 60
minutes.
