Note on Schematic Diagram:

•All capacitors are in ∝F unless otherwise noted. pF: ∝∝F 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.

•% : indicates tolerance.

•f : internal component.

Note: The components identified by mark 0or dotted line with mark 0are critical for safety.

Replace only with part number specified.

•A : B+ Line.

•Power voltage is dc 3 V and fed with regulated dc power supply from external power voltage jack.

•Voltages and waveforms are dc with respect to ground under no-signal conditions.

no mark : PLAYBACK

( ) : RECORD

∗: Impossible to measure

•Voltages are taken with a VOM (Input impedance 10 MΩ). 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.

E : PLAYBACK

j : PLAYBACK (ANALOG IN)

l : RECORD (DEGITAL IN)

•Replacement of IC801 used in this set requires a special tool.

•The voltage and waveform of CSP (chip size package) cannot be measured, because its lead layout is different form that of conventional IC.

Note on Printed Wiring Board:

•X: parts extracted from the component side.

•Y: parts extracted from the conductor side.

•x : parts mounted on the conductor side.

•z : Through hole.

• : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

Caution:
Pattern face side:	Parts on the pattern face side seen from
(Conductor Side)	the pattern face are indicated.
