14 months later...
It's been over a year since I last played with this set. My new-year resolution was to FINISH sets I've already started on... instead of starting on new ones. So, last night I decided to put this one back on the bench.
Last time I ran it, I was having a video problem. I had changed several resistors that were off spec with no luck and also tried 3 different 12BY7's. Well, it seems those 3 tubes really bit me in the ass! Come to find out, none of the three tubes were any good! I took one from a working set, and the video came back!
After I got the video last night, I started making adjustments here and there. I broke one of the convergence pots... great! Had to change the 6GH8 to get color to come in and it played "okay". The color level control seems to have some dead spots in it, so it will need changing. However, when it's turned up, the colors are quite rich. Then I went to bed.
Today, I turn it on and now have an odd problem. The picture is rolling... horizontally! I don't think I've seen that before in a set. Tried changing the sync and horz tubes (with tubes from another set) and it doesn't help it any.
Any thoughts on a picture rolling sideways???
UPDATE: Picture rolling sideways was due to a bad solder connection at the sync tube socket.
I'll still be needing to make various adjustments, clean some controls, replace the broken convergence pot. I'll get a picture posted of what I have so far later this evening.
