My Galaga has a nasty 60hz buzz in the speaker. I've heard some people say this can be caused by some switching power supplies; I have an original PS. I also saw some recommendations to rebuild the PS board. This is the first Midway machine I've done any work on, but it looks like it has something like the Atari AR boards to clean up power & amplify sound, so that could be it. I see huge caps on that and don't see any kits readily available.
Is there some place I can get a PS rebuild kit, or should I just upgrade it to a switcher?
