• % : indicates tolerance.
• f : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
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.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
