Note on Schematic Diagrams:
• All capacitors are in
µ
F unless otherwise noted. (p: pF) 50 WV or
less are not indicated except for electrolytics and tantalums.
• All resistors are in

W or less unless otherwise specified.
•
f
: internal tolerance.
•
C
: panel designation.
•
A
: B+ Line.
• Voltages and waveforms are dc with respect to ground under no-
signal (detuned) conditions.
no mark : Power on
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production toler-
ances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler-
ances.
• Circled numbers refer to waveforms.
