Here's my Tandem, I recapped everything, get good sound but terrible picture. I just went and reflowed every solder joint on the set just to see if it would help and it didn't. Ive swapped out 3 of each tube with no difference, I've tried spraying the tuner down with tuner wash that made no difference either, I also changed the selenium diodes and used new style ones that made no difference, I hooked up a bar generator to give you an idea. It's set to 9x3

1st pic is "Purity" , 2nd is "Dots", 3rd is "Cross Hatch" 4th is "Horizontal Lines" 5th is "Veritcal Lines" 6th is "color bars" 7th is "gray scale color bars"
