DIAGRAMS

Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and
specified.
•
: internal component.
f
• C : panel designation.
• H : adjustment for repair.
Note:
The components identi-
fied by mark 0 or dot-
ted line with mark 0 are
critical for safety.
Replace only with part
number specified.
• A : B+ Line.
• Total current is measured with no cassette installed.
• Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
