When I first purchased this set the previous owner he told me when had plugged it in and turned it on and he said it started smoking. Needless to say I was concerned but, not discouraged. Hopefully the smoke was friendly smoke and not the transformer or filter choke. When I got home and pulled chassis from cabinet I found that the brightness control and the on-off / volume controls were frozen and they had been turned around and around pulling the connecting wires from there connections wrapping the wire with a resister attached into a ball around the pots. It appears that what ever was used to lube these controls has a tendency to dry up freezing the controls in position. On my other National TV-7M all of the controls in the front are very stiff and frozen in the rear probably because those are seldom adjusted. I was reading a very early videokarma post from 2003 where the owner of the exact same TV needed to disassemble clean and reassemble his controls because they were frozen solid. I am hoping I can get by just using Deoxit to loosen these controls without having to open them up. I saw on Phil Nelson’s website he had to take one of these controls apart to make a repair. From the picture I saw they seem to be the friction pad type. Are these more fragile than other types? What’s the best type of lube? I have some dielectric silicone compound would that work? I think I have everything I need to get started. I am curious see Bob’s restoration of his TV when he gets time to start on it. I am sure it will be very informative. Maybe we can compare notes. I Don't want to hijack Bob's post but,my question seems related to the topic. Any advice or comments would be greatly appreciated.

Regard’s
