W or less unless otherwise
specified.
•
f
: internal component.
•
C
: panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
• Voltages are taken with VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production
tolerances.
