W or less unless otherwise
specified.
• f : internal component.
• 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 (detuned) conditions.
•Voltages and waveforms are dc with respect to ground in
service mode.
•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.

Note:
The components identi-
fied by mark 0 or dot-
ted line with mark 0 are
critical for safety.
Replace only with part
number specified.
Note:
Les composants identifiés
