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 you can, look on the top side of your chassis,
on mine on the section that holds the tuner there is on top a round looking antenna / inductor / wire wound inductor looking thingy,, my code 121 calls it T1.
one of my wires is on this short little doo dad is hanging doing nothing. its tinned like it was soldered somewhere so i assume it broke off during my handling. can you put up a couple pics of yours.?
Sure...can you show me a pic of the general area so I know what you're looking for? I have a ton of pics (355 and counting lol) but can take more if I don't have what you need. Here is a pic of the top of the turner sub-chassis, but it doesn't have anything like what you're looking for.
I don't know why, but every time I try to reply to one of your posts I get the quote of the post from Radioroslyn.
