Notes

※

1. Internal input resistance of volt-ohm meter should be higher than 10k-ohms.

テスターは、入力抵抗

※

2. Adjustments should be made in case of the PC Board or Transistors being changed.

Ω以上のものをお使い下さい。

10k

調整はPCボードあるいはトランジスタを交換した場合に行って下さい。

※

3. After feeding 1～10 watts output for about 15 minutes, check bias adjustment again.

出力1～10ワット前後で通電動作させた後、バイアス電流を再チェックします。
