Note on schematic diagrams.
• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or
less are not indicated except for electrolytics and tantalums.
• All resistors are in Ω and
• C : panel designation.
Note: The components identified by mark 0 or dotted line with
mark 0 are critical for safety.
Replace only with part number specified.
• A : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 3 V and fed with regulated dc power supply
from battery terminal.
• Voltages are dc with respect to ground under no-signal(detuned)
conditions.

• 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 toler
ances.
• Circled numbers refer to waveforms.
• Signal path.
