• C : panel designation.
Note: The components identifi ed by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specifi ed.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.

• Voltages are taken with VOM (Input impedance 10 MΩ).
• Circled numbers refer to waveforms.
