as far as the wiggle it could be where you are at in tuning range , if you reduce the agc it may improve this as well and reduce the wobbly effect .

Thank you for the info!
I forgot to mention that the white lines are stationary, if that makes a difference. I still don't have access to a CRT tester/rejuvenator. Almost bought on on EBAY, but then thought I might only use it once on this set and never use it again...I don't know if I've caught the "TV bug" yet..if I have, it's going to have to continue on much smaller sets! If you don't have a spare brightener, if you could tell me what to look for, I see there are tons of them for sale on EBAY pretty inexpensively. My only concern would be blowing out the CRT I have left and then being back to nothing. But if they are pretty safe, it might be worth a shot. It's not like the CRT is going to get better all by itself..and it may be a long while, if ever, before there's anyplace to send it off for rebuild.
I was running the TV off a VCR/DVD combo with RF output..but I can't get the DVD side to work. So I was watching a VHS tape. I remember VHS wouldn't always put out the best picture even on modern color sets, particularly when they started playing around with copy protection.
My DuMont set has a "local/distance" switch on the back which I believe has to do with the "gain". I had it set to "local". When I switched it to "distance", the whole picture would start to roll.
