6-4. PRINTED WIRING BOARD

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 1/4 W or less unless otherwise specified.

% : indicates tolerance.

f : internal component.

C: panel designation.

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 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.

Circled numbers refer to waveforms.

Signal path.

E : PLAYBACK (ANALOG OUT)

j : PLAYBACK (ANALOG IN)

l : RECORD (DEGITAL IN)

Abbreviation

CND : Canadian model

FR

: French model

HK

: Hong Kong model

JEW

: Tourist model

*IC502 and IC801 are not replaceable

The voltage and waveform of CSP (chip size package) can- not 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.

b: 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.

Parts face side:

Parts on the parts face side seen from

(Component Side)

the parts face are indicated.

 

 

Main board is four-layer printed board.

However, the patterns of layers 2 and 3 have not been in- cluded in this diagrams.
