extremely poor focus

I am hoping that this means you have cablevision coaxial cable hooked up to this set and not what it sounds like... I'm sure that there would be a lot more collapsing than vertical sweep if the antenna were plugged into a 110 v.a.c. wall socket.

But seriously, the focus and contrast improving with use is no surprise at all. I have found that if you luck out and get an old radio or television to play for more than a few minutes after decades of dormancy, the more you let them play the more bugs work themselves out. I'm fairly certain that this is due to the old capacitors sort of re-forming (rejuvenating) themselves which takes a bit of time.

I have only read a small amount on the subject of whether or not capacitors can even be "re-formed". There is a process to this in which I am sure that there are already threads on, and it goes way beyond simply plugging a set in. It seems to always be debatable whether or not old caps can be used, or more so trusted. As an owner of two TV sets, and quite a few radios over 50 yrs. old with all original (or mostly) caps I can say at least that they CAN last a VERY long time. Most particularly electrolytics....
