Title: wh20 board for topper lights
Post by: Cow Corner on February 04, 2013, 11:51:40 AM

Looking at buying another wh20 but the board for the topper lights is cactus and at this stage it is stopping me from buying the game.
Are these boards for sale anywhere or are they able to be reconditioned?

I am about 2/3 finished a replacement for this board BUT the usual issue with them is the bridge rectifiers cark it so I reckon it would be an easy fix. I wouldn't let that minor issue stop me from buying it as long as the board is actually in the machine (or at least with it).

You can see in the drawing below I have replaced the bridges with 3A diodes to eliminate the issue. The hold up with this board (I have been on it for over a year now) was getting supplies of the darlington output transistors but I now have those in stock so I can proceed with this board.
