I also ordered some stuff from
www.twistywristarcade.com (Riptor on KLOV forum), mostly for the Q*bert but also some other parts.
Among the stuff:
- connectors and trifurcon pins and polarizing keys for them
- new edge connector
- pot for the PSU board
- fuse holders for the power brick
- fuse kits for the brick and PSU board
- 27V 10W zener diode.....for some experimenting

Most important though: a volume pot for the aux panel and 3 used but original and cheap ballasts for the fluorescent tube. I figured at this price having 2 on stock would be nice.
Before you know it a total order like this is almost 100 bucks incl. shipping.....
Riptor is awesome....he refunded 2 bucks because the shipping was a little bit less than the site calculated....kinda nuts for 2 bucks, but it shows the kind of guy he is....like that for future business.
I did not order his rebuild kit for the PSU board. The reasons:
- all the caps on my board are still fine
- all the diodes on my board are still fine
- I think replacing the 30V zenerdiode by a 27V or even 24V one is totally the wrong thing to do. It only means more heat being generated on the PSU board.
I am still looking for a different solution though....either with the 27V 10W zener (this is a stud mounting diode which must be installed on a heatsink) or using a LM350 but more on that later)
- silicon TO-3. I stick to mica and grease as long as I can. Picked up 20 mica's at my local electronics dealer for just 10 cents a piece. It was all he had on stock and I mentioned he'd have to order new one's now....he replied he didnt't know if he would because they barely sold anymore. By the way I've been searching for votlage regulators and transistors in TO-3 format last weekend and it seems that slowly but surely, these things are starting to become extinct.
SMD is taking over I guess.....
Anyway, I'm not saying it's a bad kit and for some people it will be a great solution but not for me.
I do have some doubts about the other semi-conductors on the PSU, following the "crash" of the 5V section when I hook up the main board but I ordered these at a new address I found in The Netherlands:
https://www.distrelec.nl/elfa3~nl_nl/The site isn't as comfortable as f.i. RS online, but this company allows you to even buy resistors per piece and shipping costs is only 5,50, free if you order above 50 euro. And you can buy as a consumer there too, no need for a chamber of commerce number.
They also have good quality (Panasonic and Rubycon) 105 degr. C caps.....
