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 W and
1/4
W or less unless otherwise
specified.
¥C: panel designation.
¥U: B+ Line.
¥ Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
¥ Voltages are taken with a VOM (Input impedance 10 MW).
Voltage variations may be noted due to normal produc-
tion tolerances.¥ Voltages and waveforms are dc with respect to ground under no-
signal (detuned) conditions.
no mark : FM
¥ Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler-
ances.
¥ Circled numbers refer to waveforms.
¥ Abbreviation
GREEN : Illumination color
AMBER : Illumination color
