Here is where I am at so far, very little progress since October as Ive been busy with other tv projects. Fired this set up all the way on November 1st, There was no video but the color was there, picture was stable. Brightness control would have no effect. When powering off the set for a split second you would see a good NTSC picture. The "AGC Keying Sync Sep Noise Canceller" 6BH11 looked cooked. I tried another tube and got a decent picture. Powered the set up last week and here we go again with no video. Then I found the burst amp tube (6EW6) looked cooked. Replaced it with a known good 6EW6. The Video is back but the green is at full blast with retrace lines and the green screen control has no effect while blue and red seem to be uneffected. Im worried it might be the delay line but im not sure. CRT test ok. This weekend I hope to pull the chassis and take some measurements. So I'm up for sugestions.
