There is a tech somewhere in brisbane that when he comes across a wpc 95 with a reset issue replaces the bridge, large caps and the voltage regulator. but he replaces the fixed 5 volt reg with a adjustable reg.
to do this he cuts tracks and drills holes in the pcb to accommodate the diferent pin configuration and trimpot and resistor for the reg.  !!@

He does this because the machine still resets after he changes the large caps and bridge. I have said it a million times, just replace another 2 100uf 10 volt caps and it will work fine for another 10 years.

I have seen this on 3 boards and they have all come from the same seller.
