For Schematic Diagrams.
Note:
• 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

• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
Note:
The components identi-
fied by mark 0 or dot-
ted line with mark 0 are
critical for safety.
Replace only with part

• A : B+ Line.
• B : B+ Line.
• Voltages and waveforms are dc with respect to ground un-
der 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.
• Circled numbers refer to waveforms.
