OK, that makes sense. None of those were changed. There's a bunch of them. I'll let you what I find.
Thanks.

OK, I jumpered each 1500pf bypass cap with some clip leads attached to a 1500pf mica cap. It wasn't as hard as I thought it would be. Still no joy. I'm suspecting the tuner.
Anymore ideas I could try?

Even though the IF tubes test ok, I would try swapping them out to see if the symptoms change.

I take it you found no hot spots that changed the behavior when touched.

How does the picture react as you turn the Picture control up and down? Do the streaks move? Or is there only a contrast change?

OK, I swapped out each one, one at a time with another NIB RCA 6AG5 that tested like new. Still no joy. Basically the same with each swap out. Good idea though.
