Hey all, thanks for the response. It was actually pretty simple I was just paranoid and wanted to make damn sure I was doing it right, because of all the work/time it's taken to restore this sucker. It's actually hilarious that I've been spent all this time and $$ restoring this blasted Qbert and I end up buying a working one for $200 from a dude just the other day - that's the way it goes I suppose.
BTW
The knockers not bad at all with the switching PS, it's just a bit more tame than w/the regular power board which I definitely prefer - especially when I'm trying to sleep and my wife is playing Qbert all night.
