Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
(Page 43) 50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and
specified.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : FM
( ) : PB
< > : REC
[ ] : CD STOP
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
