Could also be bad fluctuations in your wall current. I have that problem, and it drives me nuts. My sets(when I run two or more at once) will rapidly and randomly bloom at the same time (lights also flicker in step to it)...A friend of mine experiences the same thing and thinks it is because of smelting operations running on the same power grid in the area.

Well, I replaced all the electrolytics with brand new parts I ordered from Digikey when I first started working on the set a couple of years ago, so I guess I'd suspect the wall current. Maybe I could replace the capacitors on either side of the main power choke with larger values and see if that works. 40uF and 80uF seem pretty small, to me, but those were the original values.
