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

Note: The components identified by mark 0 or dotted line
with mark ! 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
under no-signal conditions.
