This kit contains replacements for likely failure parts of the AFM strobe board.
COMPONENT (BOARD LOCATION)
1 4A 600V Triac (Q1)
6 1N4007 diode (D1, D2, D3, D4,D5,D6)
2 Film Capacitors Repl (C5,C6)
2 capacitors 100uF 100V (C1)(C2)
1 Optoisolator MOC3011 (U1
1 trigger transformer
With this kit, you should be able to repair the board.
To replace C1, we recommend using the capacitor originally at C2. The Williams design runs these 100V parts at 150V in the C1 location, which causes failure. Our suppliers will not warranty parts in this location. However, the original part at the C2 location will be fine.
note: capacitor supplied may vary
