Philco 50 (Nathan's)
#23

OK - so where did we leave off?

Right! Getting to the point where we can power it up on a variac for the first time and see if there are signs of life.
I like to do that before replacing too many components so that I can replace things in testable chunks (reduce the amount of wiring I need to check if I make a mistake).

Filter caps are a must to replace first though. Also that one resistor that measured open.

I typically use a terminal board - in this case with a standoff - for the filter caps. I know a lot of you guys restuff them, which certainly looks nicer underneath, but I figure somebody (maybe me) will be replacing them someday. And since it's an easily reversible change (I mount using an existing hole) that's what I do.

Here we are with the open resistor and its siblings replaced as well:

Now it's time to put the tubes back in. All of the tubes that it came with tested good. Yay!

These look like these could be the original 24 tubes that this radio came with. It seems like there are still quite a few globe 24 tubes around (not so many 80 tubes - mine came with an ST version, so definitely replaced).

Slowly turning up the voltage....and....we have lift off at around 80V!

So that's great news - it receives a couple of the local strong stations and at pretty decent volume.
