•  All capacitors are in 
μF unless otherwise noted. (p: pF) 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 
specifi ed.

A : B+ Line.
•  Voltages and waveforms are dc with respect to ground 
under no-signal (detuned) conditions.
  no mark : AUDIO IN
•  Voltages are taken with VOM (Input impedance 10 M
Ω).
  Voltage variations may be noted due to normal production 
tolerances.
•  Waveforms are taken with a oscilloscope.
  Voltage variations may be noted due to normal production 
tolerances.
•  Circled numbers refer to waveforms.
