Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV
or less are not indicated except for electrolytics and tantalums.
• All resistors are in Ω and

• Voltages and waveforms are dc with respect to ground under
no-signal (detuned) conditions.
no mark : PLAY
: Impossible to measure

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production toler-
ances.
• Waveforms are taken with a oscilloscope.

Note on Printed Wiring Board
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side A)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Side B)
the parts face are indicated.
• MAIN board is multi-layer printed board.
However, the patterns of intermediate-layer have not been in-
cluded in the diagram.

Replacement of IC400 on MAIN board requires a special
tool.
