1/4
W or less unless otherwise
specified.
¥ % : indicates tolerance.
¥U: B+ Line.
¥H: adjustment for repair.
¥ Power voltage is dc 9 V and fed with regulated dc power
supply from external power voltage jack (J4).
¥ Voltages are dc with respect to ground under no-signal
conditions.
¥ Voltages are taken with a VOM (Input impedance 10 MW).
Voltage variations may be noted due to normal produc-
tion tolerances.
¥ Signal path.
F: AUDIO
J: RF
