Now available on my site. (https://mypinballs.com/electronics/store.jsp). The first version of my remake board for the waterfall chase lamps on whitewater. Complete redesign. Many improvements over the original including proper sync to when the lamp effects should be on and off and no more 'janky' locked on lamps at boot or in test etc. Plus you can use regular/easy to source 12v wedge bulbs now to instead of the super expensive 14v ones (if you can find them!!)

£80 plus postage. (Tracked international post.) I have a small run of them first for batch 1, so first come first served.

That's great that you can still get the ok on the us, but elsewhere it is a different story most of the time, hence me adding some options on my board to use alternatives. Of course you can still run the #194s if you have supply of them and they are cheap, just you now have future proof options to with some of the other bulb types such as #504 common here in uk and europe.

The main improvement for my board other than bulb usage is the fact the board is now more 'intelligent' than originals. You no longer have a problem with the lamps locking on solid at boot in random patterns to when you enter the test menus. This puts unnecessary load on the bulbs and drivers at certain point and also looks a mess. By utilising a design that can read when the cpu control stops the board can disable the lamp string and then reenable once signals start up again. This in my view is what Williams should have done and intended for the design of the topper in the first place.

See here for a quick test video showing then lamp string being enable and disabled at certain points. ie at boot the full lamp string is off until the playfield GI turns on
