I put everything together and it still worked although a full setup was needed after applying Deoxit to all the controls and tuner. You can't see it but I installed brass threaded inserts in the cabinet screw holes for the back cover. The original screws were very short. I don't know why TV manufacturers always use tiny, short screws for backs that strip out after a few removal cycles. A tube TV usually requires frequent service. Now I can remove the back as often as I need to without stripping the wood as the back cover screws now go into brass. Think long term serviceability.

I never had the correct knobs for the volume and contrast controls. I ordered some reproductions and the fit and finish are excellent. I highly recommend them. The only trouble is that the reproductions are maroon where as the originals represented by the channel selector are red. Oh well, I can live with that. At least I have the correct size and style of knobs.

So now I have what looks and feels like a brand new TV. I am very pleased with the whole project. There is just one performance issue that I could use a little help with. After the set has been on for about fifteen minutes or so, it develops a slight but continuous vertical jitter that cannot be corrected with the vertical hold control although the hold control works within a normal range. All paper caps and all resistors were replaced in the sweep and high voltage sections when i restored it in 1999. It has been very reliable in the past 13 years needing only a ballast tube and correction of a heater to cathode short in the picture tube which I blasted away with my old B&K CRT tester.
