I think what you are referring to is the bridge rectifiers not being fused between the transformer and the BRs.

I got an upgrade kit including the 30,000uF capacitor, 2 new BRs and all the necessary fuses and holders from a Steve Kulpa on ebay. Pretty sure it was from him...

This place sells partial and complete circuit board rebuild kits and other pinball stuff.

super8man/SealClubber gave you nice options .. do the upgrade to your current board yourself much cheaper .. or buy a replacement board from a vendor suggested. That's what great about this place .. different people .. different ideas .. different options .. you pick

My suggestion was chosen because they are a major vendor I know to be reliable is all.

And, thanks to this posting about the issue of fire, I finally got around to installing my own fuse panel for the bridge rectifiers(!!). I bought them about 2 weeks ago... I feel a whole lot better when it's running now.

Steve Kulpa will repair your boards and sells some.
Tom Callahan at www.pin-logic.com also sells and repairs boards. He will also help you with troubleshooting. Purchased from both, can't go wrong with either.
