After that nightmare Airline movie dial chassis, thought I'd tackle something a bit less messed up. Working on a 41-230 with a bad audio output transformer. Can anyone recommend a suitable new manufacture replacement that can be ordered online (like from Radio Daze or AES)?
Here's the schematic. It's #42.

Thanks!
Hey buddy you got to work on that addiction!!!!!
Well you need about 10K for the plate load so I found this which is 25K at 8 ohms on the secondary. So with the assumption that your spkr is 4 or less ohms that will put us in the ballpark. Did see a few others but they were 2 or 3 times the price.

Ha! I actually had this one out of the cabinet before I got the movie dial set. When I found that one, this little Philco got pushed off to the side.
This is real tiny little transformer. The body is only about 1" wide, so not a lot of room under the chassis. I'm seeing 700 ohms on the schematic. I certainly trust your judgement but before I order one I just wanted to confirm that the 25K you suggested will work?
We are speaking two different languages one DC resistance (on the schematic) and AC impedance (the 25K).
Ah! That makes more sense
