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 / W or less unless otherwise

specified.
• C : panel designation.
(Page 35)
• U : B+ Line.
• Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
• Voltage and waveforms are 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.
