THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
Common Note on Schematic Diagrams:
• 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 Ω and 1 /
4
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 9V and fed with regulated dc power
supply from battery terminal.
• Voltages are taken with a VOM (Input impedance 10 M Ω ).
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.
• Circled numbers refer to waveforms.
• Signal path.
