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 ⦠and 1/4 W or less unless otherwise
specified.
⢠¢ : internal component.
⢠C : panel designation.
⢠U : B+ Line.
⢠Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
⢠Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : FM
< > : TAPE PLAYBACK
â : Impossible to measure
⢠Voltages are taken with a VOM (Input impedance 10 Mâ¦).
Voltage variations may be noted due to normal production
tolerances.
⢠Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
⢠Circled numbers refer to waveforms.
⢠Signal path.
F : FM
f : AM (MW)
E : TAPE PLAYBACK
