WTB: Williams WPC Driver board

[[e-mail]]

Looking for a 100% working WPC driver board to be used in a Twilight Zone. Rottendog boards just do not cut it. Two Rottendog boards and still only have 21V AC at J105 and the flippers are not flipping. Please let me know price/availability.

Thanks,

Craig

Twilight Zone is a Fliptronics board. The DC flipper power comes off of
that Fliptronics board. But you are right that you need to have
sufficient AC for it to work.

The AC supply does feed through the power driver board. The AC comes in
J102, then back out J104/105 into J901 of the Fliptronics board.

But the driver board does nothing to that AC, other than fuse it. It is
just a pass through. If the AC is off, it is either the transformer,
the connectors, or the fuse / fuse holder.

Are you sure you are measuring AC and that you are measuring from pin
to pin (and not pin to ground)? The 50 VAC is J104/105 pins 1 & 2.

There is also 18 VAC on J104/105 pins 4 & 5 (if I am reading the
schematic properly).
