For schematic diagram:

- Caution when replacing chip parts.
New parts must be attached after removal ot chip.
Be careful not to heat the minus side of tantalum capacitor,
because it is damaged by the heat.

- All resistors are in ohms, /4W (Chip resistors : lmW) un-
less otherwise specified.
kfl:1000§2,Mfl:1000kQ.

- All capacitors are in (AF unless otherwise noted. pF : uuF
50V or less are not indicated except for electrolytics and
tantalums.

- All variable and adjustable resistors have characteristic curve
B, unless othenlvise noted.

- E : nonflammable resistor.

: fusible resistor.

: panel designation.

: internal component.

: adjustment for repair.

: B+ Line.

: B- Line.

' Circled numbers refer to waveforms.

- Voltages are do between measurement point.

- Readings are taken with a color-bar signal on DVD refer-
ence disc and when playing CD reference disc.

- Readings are taken with a digital multimeter (DC 10Mn).

- Voltage variations may be noted due to normal production
tolerances.
