Found a couple of different prints both claiming being code 125.

One lists the rectifier 35Y4, Another - 35Z5, but the tube I have is 35Z3.
Checked the connection, seems to be correct for this tube.
The soldering on it is mostly neat, might be factory, the one that has been reworked is due to the caps change. So not sure if the tube is original or not.

The tube has no pilot lamp tap on the filament so the Candohm has a third pin (sch and photos of radios I see show 2-pin Candohm). The third pin is used to create that tap.
It clearly has been re-soldered. I think it is OK.

One sch that shows 35Z5 also shows 50L6 output tube (the one I have).
The sch showing 35Y4 shows 50B5 tube (the pins are different).

I think other than the antenna, the rest is fine.
