When I first got this set, the major problem it had was it would produce no picture, just a blank raster, the problem turned out to be caused by this burned out little choke coil in the IF sections somewhere, probably did go bad early on, and just sat ever since.
The set worked fine for a while last night after I changed that resistor, but I turned it on today and got a similar intermittent horiz sync problem. I took it apart and ran it again poking around inside the chassis, this time that horiz AFC diode seemed to be causing the trouble, I swaped it with 2 1N4007 diodes I had (bought a pack of them several years ago and been using them to replace those selenium rectifiers in power supplies - those were my last 2), I wasn't sure if it was going to work at all or not, but it did and is still going, I'm hoping this is the last of the horiz problems with this set...
