Have you tried disconnecting the beeper in case bus noise is leaking across somehow?

I remember that other 80’s computers made these kinds of sounds while processing. I know our Philips P2000T did and later our Amstrad CPC464 as well…. Cheap analog electronics I guess… I did double and triple check the polarity of the caps, so I don’t think that’s the problem.

That's actually kind of cool. But, if you want to get rid of it, maybe double check that you put your electrolytics in with the right polarity. —b9
