Notes. ※1. Internal input resistance of volt-ohm meter should be higher than 10k-ohms.
テスターは、入力抵抗 10kΩ以上のものをお使い下さい。
※2. Adjustments should be made in case of the PC Board or Transistors being changed.
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. Afer feeding 1～10watts output for about 15 minutes,check bias adjustments again.
