SO I've had this thing for 18 years and it has given great service, and continues to, BUT worried the PSU may be going, and I'm not a pro at hardware so looking to you all.

SO perfect performance with a 1 slot, flawless, so thats still good.

BUT with a 4 slot 1 or 2 slots routinely have garbled graphics that go in and out, YES I have had the board checked twice and each time runs flawlessly on their cab without symptom. I have tried ALL variations of carts, still no go.

THE PSU POT IS TURNED ALL THE WAY UP symptom still there

Any ideas for a fix? New power supply? If so where to get? How much and how hard to install? Links always helpful.

OR is there a voltage converter that I could just go through to get to US current?

Thanks so much everybody

PS the more I think about it 4 slots have ALWAYS been wonky over the years, thought was dirty carts, worn cart slots, but last 3 years its worse, 2 slots play flawlessly , 1 or 2 others have garbled graphics

1) If 1-slots work, your cab is prob wired for JAMMA, not MVS. 2) You should use a multimeter to check your voltage. 3) You're going to damage something if you turn your PSU 5v pot all the way up. 4) A 100v voltage stepper is not a substitute for a power supply.

thanks daskrabs, nah certain it is wired for MVS, 4 slot ran well for many years. Actually the POT was turned up all the way when I got it. If I turn it down, the board starts up, then just dies. Can someone walk me through checking with a multimeter? Thanks

turns out was a loose connector on the board, changing angle and tightening pins has it back working 100% BUT board no longer holds scores and settings in memory:)
