>any particular reason for the "A" designation?
Not sure.

Wouldn't condemn it yet. Remove the 5X4 tube and measure the AC voltage from pin 3 to pin 5 at the socket. Should see about 600vac. You can leave it on for 10-15min (again w/o the 5X4 inserted) and feel if the power transformer gets hot. If it makes hv and stays cool I would not replace it just because it's lost some wax.
> The rear is a 32-7671T. Are these compatible?
Don't know don't have a parts catalog.
> but has a double Solar 8/8uf there- would that be considered excessive for that circuit?
Would suspect that these differing capacitor values were what was on hand at the time that it was serviced. Fortunately the values are not particularly critical. Some like 14mfd were not a standard value (8's or 16's mfd were)
> I must acquire the correct Philco electrolytic cans and the correct Philco .25mfd cardboard housing
Not necessarily there are several ways to replace what you have.

I just use the edit button on the tool bar to resize the image down to 600/325 and attach the image.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
