• All resistors are in Ω and
specified.
• 2 : nonflammable resistor.
• C : panel designation.
Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part

• A : B+ Line.
• B : B– Line.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
