Rating (DC)
0.05mV–2.5mV
* Confirm that the idling current is 0.25mV – 15mV after 60 minutes.
Note
If the measured voltage exceeds 2.6mV, cut the lead wire of R80 (L ch)
or R81 (R ch) and then check again if each measured value satisfies the
rating.

AMP ADJUSTMENTS
●
Confirmation of Idling Current
1) No signal applied.
2) Non-loaded condition.
3) Aging is not necessary.
Note)
• If the idling current exceeds 2.6mV after a power
amplifier repair, check for a defective component
before cutting the resistor.
• If R80 (L ch) or R81 (R ch) have already been cut off
and idling current does not flow, reconnect R80 (1k-
ohms) or R81 (1k-ohms).
• Q17 and Q18 are transistors for temperature correc-
tion. Apply silicone grease to the contact surface with
the heat sink.
