in each block.)
For schematic diagrams.
Note:
• All capacitors are in

and tantalums.
• All resistors are in

specified.
•
f
: internal component.
•
2
: nonflammable resistor.
•
1
: fusible resistor.
•
C
: panel designation.
For printed wiring boards.
Note:
• X
: parts extracted from the component side.
• Y
: parts extracted from the conductor side.
•
a
: Through hole.
•
: Pattern from the side which enables seeing.
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
•
∗
: Impossible to measure
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
