N te on Printed Wiring Board:
Ws: parts mounted on the conductor side.
[ t indicates side identified with part number.
e @ =: Through hole.
: Pattern on the side which is seen.
Se Pattern of the rear side
Note on Schematic Diagram:
e All capacitors are in uF unless otherwise noted. pF: wuF
50WV or less are not indicated except for electrolytics
and tantalums.
e All resistors are in Q and '/,W or less unless otherwise
specified.
A: internal component.
=m © B+ Line
[___]: adjustment for repair.
Total current is measured witn no cassette installed.
Power voltage is dc 3 V and fed with requrated dc power
supply from battery terminal.
e Voltage and waveforms are dc with respect to ground
in playback mode.
no mark: FWD, FM
e Voltages are taken with a VOM (input impedance 10 MQ).
Voltage variations may be noted due to normal produc-
tion tolerances.
e Signal path.
