DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTE:NOTE:
1. The unit of resistance ?ohm?is omitted (K=1000
1. DISCONNECT THE AC PLUG FROM THE ACohms. M= Megaohm).
OUTLET BEFORE REPLACING PARTS.2. All resistors are 1/8 watt. unless otherwise noted.
3. All capacitors are mF, unless otherwise noted
2. SEMICONDUCTOR HEAT SINKS SHOULD BE(P= mmF).
REGARDED AS POTENTIAL SHOCK HAZARDS4. The capacitor with Part No. RC-FZ9XXXBMNJ
WHEN THE CHASSIS IS OPERATING.is designed to with stand 63V.
5. The capacitor with Part No. RC-FZ4XXXBMNJ
is designed to with stand 50V.
