AMP ADJUSTMENT

/ アンプ部調整

●

アイドリング電流確認

1. 電源投入直後、

下表のＡ欄の抵抗の端子間電圧を測定し、

0.1mV 〜 10.0mV であることを確認してください。

2. 電圧が 10mV を越えている場合は、下表のＢ欄の抵抗を

カットし、電圧を再確認してください。

注意：パワーアンプ修理後に10.0mVを超えている場合は、抵抗を

カットする前に故障箇所を調べてください。

3. 60 分後、電圧が 0.2mV 〜 15.0mV であることを確認して

ください。

<Position for Adjusting MAIN (1) P.C.B.>

1. Immediately after the power is turned on, measure the

voltage across resistor terminals in the column “A” in the

table below and confirm that the measured value is be-

tween 0.1mV and 10.0mV.

2. If the measured voltage exceeds 10.0mV, open (cutoff)

the resistor in the column “B” in the table below and re-

confirm the voltage.

Attention:

If the idling current exceeds 10.0mV after a power ampli-

fier repair, check for a defective component before cut-

ting the resistor.

3. Confirm that the voltage is between 0.2mV and 15.0mV

after 60 minutes.
