• MAIN (2103)

NOTE: Warning

Parts that are shaded are critical With respect
to risk of fire or electrical shock.

NOTE:

1. Shaded(■) parts are critical for safety.Replace only

with specified part number.

2. Voltages are DC-measured with a digital voltmefer
during Play mode.

NOTES : 1. Resistance values are indicted in ohms unless otherwise specified (K=1,000, M=1,000,000).

2. Capacitance values are shown in microfarads unless otherwise (P=MICRO-MICRO FARADS).

3. Schematic diagram for this model are subject to change for improvement without prior notice.
