Hi all, I'm presently finishing off a JAMMA adaptor for a Midway Guided Missile to play it on my supergun. Everything is hooked up and working except the speakers. The Guided Missile had two speaker outputs where different sounds play through each speaker, and I was wondering how I should...

Can anyone confirm the V.Audio voltage (pin#15 on 'Midway L shape' soundboard 15 pin connector). I'm hoping it's the same as Space Invaders +12v, but I could be wrong and maybe it's +15v like some of the older Midway L shape boardsets. Thanks P

So after a few months hiatus from trying to repair this sucker, I decided to have another go this weekend. So here is my Setup: I have a Supergun which I have made a SI adaptor for (tested and works fine). I do not have any of the original roms and I am using a BRAZE multigame to help find any...
