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

W or less unless otherwise
specified.
•
f
: internal component.
•
C
: panel designation.
•
A
: B+ Line.
•
H
: adjustment for repair.
• Total current is measured with no cassette installed.
• Power voltage is dc 12 V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
Note: The components identified by mark
