Confirmation of Idling Current of MAIN (1) P. C. B.
Right after power is turned on, confirm that each mea-
sured voltage across the terminals of R1149 (FRONT
Lch), R1150 (FRONT Rch), R1153 (CENTER), R1154
(SURROUND Lch), R1152 (SURROUND Rch), R1151
(SURROUND BACK) is between 0.1 mV and 10.0 mV.
If it exceeds 10.0 mV, open (cutoff) R1104 (FRONT
Lch), R1106 (FRONT Rch), R1112 (CENTER), R1114
(SURROUND Lch), R1110 (SURROUND Rch), R1108
(SURROUND BACK) and reconfirm the voltage.
Attention
If the measured voltage exceeds 10.0 mV. after an am-
plifier repair, first check for a defective component be-
fore cutting the bias resistor.
Confirm that the voltage is 0.2 mV-15.0 mV. after 60
minutes.
