THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
Common Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted.  pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in 
 and 
1
/

W or less unless otherwise
specified.
f
: internal component.
C
: panel designation.
A
: B+ Line.
H
: adjustment for repair.
• Total current is measured.
• Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.

• Voltages are taken with a VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
