Eric:
Does the Wallace include the production changes? Some are in the vertical. I can get them to you somehow, if you like. Let me know.
I am losing confidence in re-stuffed electrolytics. They seem to introduce new problems. Perhaps some are re-stuffed with capacitors intended for other uses. Not all electrolytics are equal, as I am discovering. I have better luck by bridging them individually to find a bad one. A scope tells a good story as well. If I don't see an improvement, I am likely to leave them alone for the time being. I guess I am not a purist.
I believe that was Philco's first attempt to use a multivibrator for vertical sweep. The engineers were still learning. All earlier ones used a blocking oscillator, which is much more stable.
