Dave,
Pretty sure I can help with the 4 pin connector. When it comes to it. you can simply strap the L & H band inputs in parallel, only one of the 2 input lines is terminated at any given channel.
It is not uncommon for an old 40s vintage set to come back to life when brought up slowly on a viriac, but it will not last. A full recap is the only long term solution. I am sure Chuck A would love to do it. :-).
No fine tuning required, as the AFC control loop in the set keeps the tuning perfect! Don't know why other manufacturers did not adopt the concept.
I was never very fond of the Philco 8 position tuner, but the reasoning was sound. Back in the 1940-early 50s, there would never be more than 8 stations in any given major metropolitan area, as decreed by the FCC. So 8 was enough.
That is a great set. Same chassis as the somewhat more stylish 48-1000, but still a under-appreciated set, in my opinion.
