SCHEMATIC DIAGRAM (D-AMP)
* All voltages are measured with a 10M
Ω
/V DC electronic 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.
