Thanks Mark
I've swapped out that 25L6 and the blue glow is gone. I also replaced those ceramic tube caps with some higher rated mica ones.
The video is looking really good now
Audio not so much
Here's a
YouTube clip taken with my good camera. There's a brief clip from a Cubs game so I hope YouTube doesn't pull it!
There's a buzzing that gets really bad when these bright white on the screen. I've had this happen with other sets, but nowhere near this bad. The schematic indicates that shielded cable should be used for the contrast control, but my sets just has plain wire. I'll try putting in some coax and see if that helps tonight.
