• Waveform
For schematic diagrams.
Note:
• 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
Ω
and
1
/
4
W or less unless otherwise specified.
•
f
: internal component.
•
C
: panel designation.
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
• Voltages and waveforms are dc with respect to ground under no-
signal (detuned) conditions.
No mark : STOP
• 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.
• Signal path.
