Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. p: pF.
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and
1
/ W or less unless otherwise

specified.
• : internal component.
f
• C : panel designation.
The components identified by mark 0
or dotted line with mark 0 are critical for
safety.
• A : B+ Line.
• H : adjustment for repair.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : FM
∗
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F
: FM
f
: AM (LW/MW)
