Well, the lights started flickering again. In attached, CB 1 & 3 are a
signal unit - tandem I think is the term. I removed them, cleaned all
the contacts and checked all the wiring connections and all are fine.
After that, no flickering for a few weeks. Now it started again this

anyone knows somewhere else, I can post an image for this there.
Meanwhile, it's posted at alt.binaries.schematics.electronics and
CB #9, receptacle near the door has a lamp plugged into it and it also
flickers when the ceiling lights do. So that probably elimates CB 1&3
as the problem. Also, it might be good to say that no appliances or
heavy power users are running at the time of the flickering. I have
looked for a common activity, but they flicker night or day, and whether
anything else is running or not.
No other devices are flickering. Wind doesn't make any difference,.
The ceiling light/fan in slot #8 doesn't flicker, nor do any other lamps
plugged into receptacles.
Any other ideas what might be the problem before I go out and buy a new
