Note:
• 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

specified.
• % : indicates tolerance.
• C : panel designation.
• A : B+ Line.
• Power voltage is dc 3 V and fed with regulated dc power
supply from external power voltage jack.
• Voltage is dc with respect to ground under no-signal
condition.

Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : PB (analog)
L : REC (analog)
J : PB (digital)
