Hey Dick, I just restored one of these Philco 48-2500.
These are really neat sets - not a lot of survivors.
I think I saw the Ebay listing for the TV and if it had been near
me I think I would have bidded on it. Looks like a nicely
preserved TV.
Over on ARF, and I think here too, are several very knowledgable folks
on these TVs. Here is information on my Philco 48-2500 restoration:
