DIAGRAMS
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 Ω and
1
/
4
W or less unless otherwise
specified.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
•Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
•Voltages is dc with respect to ground under no-signal
(detuned) conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
E : AUDIO signal
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• b : Pattern from the side which enables seeing.
