>Q- to the left is code 122 prints and at no point is the on off switch tied to my rectifier tube.
In the real world, i have what is hand sketched to the right.
I did some reading and saw people talking about how to bypass the primary of the power xfrmr when it craps out.
Does it appear this mod was done here?
No.
The pins that the white wires are connected to are not connected to the tube internally.
>Q- The code 122 prints indicate i should have a dozen conductors on my transformer Pri&Sec combined. I only have 10 conductors total.
There is one single conductor that is spared back with tape on it and its been like that prior to me touching.
Methinks your power transformer has been replaced w/a generic replacement. Note the black crud by the output tubes socket. Looks like tar from the old pt.
>Q- Is there any way for me to identify other than resistance values what conductors on my xfrmr are?
The prints indicate a color code the secondary's but all i can see is a bunch of brownish cloth covered wires.
I can "almost" see a hint of color in a couple but feel like its my brain eye coordination wanting to see it.
You can tell by what they are connected to. The resistance measurements don't tell you a lot anyway. With a non original pt it will differ from the philco diagram. Your "new" pt may only have one 6.3v winding rather than the two like the original.

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!
