I wonder if this is the line frequency change thing that was going to screw the clocks up. Very doubtful, just a thought.
Scope the line and see whats going on there.

Wow how wierd is this, freaky computer printer. unplugged it an all is good.

it was on the same circuit as the tv. so now I am back to the ghost again.

funny thing, while looking for a source of AC hum, I did a check of all the tubes for HK shorts, one of the 3 6GH8's (big suprise there) and a 6UA6 (sound board) had shorts. Did not seem to matter. Of course maybe the short just as not that bad.

I have seen laser printers pull down the line when printing, enough to make fluorescent lights flicker, but I assume you weren't printing anything at the time.

correct not printing but it has been acting up somewhat, and my UPS recently died (it was not that old less than a year). perhaps the printer had been stressing it out. I just recently unplugged it from the UPS after it died and plugged directly into the same power strip that the TV was on. Lesson learned, big time.

it was not just pulling it down either, I mean it was trashing the B+, worse that when the AC comes on,which just drops the vert size a tad but this was really disturbing the heck out of the set, more like something was arcing. Flickering sound about right. oh well, like I said its just one more thing to file into what can go wrong.
