★
Unless otherwise specified, all resistors are 1608 size chip resistors.
★
Unless otherwise specified, all capacitors are 1608 size chip capacitors.
（For C334, however, please use radial parts.)
★
Flame proof carbon resistors are all 1/4W.
● 指示のない抵抗はすべて1608サイズチップ抵抗です。
● 指示のないコンデンサはすべて1608サイズチップコンデンサです。
（ただし、C334はラジアルパーツを使用してください。）
● 不燃化カーボン抵抗はすべて1/4Wです。
★
All voltage are measured with a 10M
Ω
/V DC electric volt meter.
★
Components having special characteristics are marked
s
and must be replaced
with parts having specifications equal to those originally installed.
