Note:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 V or less are not indicated except for electrolytics and
tantalums.
• All resistors are in Ω and
1 / W or less unless otherwise

specified.
• % : indicates tolerance.
• f : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
Note:
The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.
• C : panel designation.
• 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.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
