supply from battery terminal.

• 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

• Voltages and waveforms are dc with respect to ground

under no-signal (detuned) conditions.

• Voltages and waveforms are dc with respect to ground in

playback mode.

• Voltages are taken with a VOM (Input impedance 10 M

Ω

).

Voltage variations may be noted due to normal produc-
tion tolerances.

• Waveforms are taken with a oscilloscope.
•  Circled numbers refer to wave forms.
