The power supply and sweep sections should be the least of your issues. These are rugged sets and I cant wait to see how yours turns out.
Mine must have a replacement FBT, it looks silicone-encapsulated. It worked for reliable garage-shop watching in the 90s, color sync was touchy and tuner would flake into hash-lines some times, especially on UHF, where all but one of the local channels was. I just left it on the UHF channel I watched the most.
