Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
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.
• C : panel designation.
• U : B+ Line.
• H : adjustment for repair.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.
no mark : PB
( ) : REC
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
