Note For Printed Wiring Boards and Schematic Diagrams
•
MAIN board is multi-layer printed board.
However, the patterns of intermediate-layer have not been in-
cluded in this diagrams.
•
Lead Layouts
Note on Schematic Diagram:
•
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
1
/
4
W or less unless otherwise
specified.
•
f
: internal component.
•
C
: panel designation.
•
A
: B+ Line.
•
Total current is measured with MD installed.
•
Power voltage is dc 1.5 V and fed with regulated dc power
supply from battery terminal.
•
Voltages and waveforms are dc with respect to ground in
playback mode.

∗
: Impossible to measure
•
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.

X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
