My SID UFOs started making horrible sounds when they fly so I did some research and found this page:

I replaced the 76477 at H2 and that did the trick.
Further reading however revealed that the UFO is supposed to make a sound when you hit it too. Mine has always been silent and I never knew the difference. I looked it up on youtube and sure enough it does.
So, following this guide, I replaced the lm3900's at M5.
No change.
I replaced the 74174 at E5 and the 7417 at F5.
No change.
Anyone know what else I can try?
