SCHEMATIC DIAGRAM (DSP 2/2)
★
All voltages are measured with a 10M
Ω
/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。
★
