Note:
• 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

W or less unless otherwise specifed.
• 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.
• B : B– Line.
•Voltages are dc with respect to ground under no-signal conditions.
no mark : Power on
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.
F : AUDIO
