Very nice score Chris!
I picked up one a while back but it had been painted black!

Have you got it working yet?

Looks good. Do you think it might have refinished by someone who knew what they were doing? It looks almost too good to be the original.

I like the depth of the finish.

No, it's the original finish. I cleaned it with Howards Restore A Finish before I took the pictures. It looks like it has been well taken care of over the years.

Very nice set. looking forward to some chassis shots.

No, but I tested the CRT in a working set, it's like new, a Tung Sol replacement tube!

One reason I haven't been motivated to work on it is the well known high voltage fade problem on these sets, I have another one with that problem.

[DaveWM]

can you elaborate on the fade problem, I have not heard of that (but then I am new to tv's).

The 7" Philcos (except the 48-700) have a problem where the High Voltage drops off after 15-20 minutes of operation, pretty much everyone who has one has experienced the problem including me.

Some have speculated that they must have had the problem since they were new but that seems unlikely.

There was an exact reproduction made of the transformer and it had the same problem.

The transformer can be replaced with a solid state HV module but they are very expensive.

There's a thread on the problem here:

I think there was a more in depth thread on the subject but I can't find it.

And a page on making the SS replacement: http://www.myvintagetv.com/philco_hv.htm

Google the model number and you'll find more on the subject.

Has anyone tried adapting a surplus Motorola electostat coil and circuit to these sets.
