Standard multiball is 4 balls. I believe that’s even true for Ultimate Challenge. The only time it’s a 6 ball is Super Multiball (“Send backup units!”) during Super Game. That’s why if you never play Super Game you will eventually get a Trough 2 credit dot.

It sounds almost for sure like you’re probably having trough opto issues. I had the same thing happening on my game, replaced the trough optos and it cleaned up the issue. Dredd is an absolute bastard for opto issues.

It’s 4. For sure. I just ran it on my no credit dot all new optos machine.

I don’t think so, because he’s getting 5 balls. I bet his trough 1 is flaky, that always seems to be the one that goes bad for me.

HIGHLY suggest the Great Lakes Modular ones. They fit really nicely and work like a charm. http://www.greatlakesmodular.com/

Oh that sucks. He makes great stuff. Maybe try K’s Arcade. GLM directed me there after I tried to order something he didn’t have in stock.
