SCHEMATIC DIAGRAM (DSP 2/2)
All voltages are measured with a 10MΩ/V DC electronic volt meter. Components having special characteristics are marked s and must be replaced
with parts having specifications equal to those originally installed. Schematic diagram is subject to change without notice.
電圧は、内部抵抗10MΩの電圧計で測定したものです。 s印のある部品は、安全性確保部品を示しています。部品の交換が必要な場合、パーツリストに記載されている部品を使用してください。
本回路図は標準回路図です。改良のため予告なく変更することがございます。
