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
1
/
4
W or less unless otherwise
specified.
•
C
: panel designation.
•
U
: B+ Line.
•
H
: adjustment for repair.
• Power voltage is dc 3 V and fed with regulated dc power
supply from battery terminal.
• Voltage is dc with respect to ground under no-signal
condition.
no mark : PB/REC
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
