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

W or less unless otherwise specified.
•
f
: internal component.
• C : panel designation.
• A : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 3 V and fed with regulated dc power supply
from battery terminal.
• Voltages and waveforms are dc with respect to ground under no-
signal (detuned) conditions.
no mark : PLAY
( ) : REC
• Voltages are taken with a VOM (Input impedance 10 MΩ).
• Voltage variations may be noted due to normal production toler-
ances.
• Voltage variations may be noted due to normal production toler-
ances.
• Signal path.
E : PB
a : REC
F : MIC
Note on Printed Wiring Board:
• Y : parts extracted from the conductor side.
• b : Pattern from the side which enables seeing.
