■ SCHEMATIC DIAGRAM (DSP(1)-1)
* All voltage are measured with a 10MΩ/V DC electric volt meter.
* Components having special characteristics are marked Z and
must be replaced with parts having specifications equal to those
originally installed.
* Schematic diagram is subject to change without notice.
