The ohm values of the old transformer don't really tell anything other than whether it is open or not. What is important is the impedance and turns ratio. Impedance will determine how good of a match to the plates of the 6J5's it will have and turns ratio determines the amount of signal that is applied to the grids of the 6F6's.
I'd go ahead and grab the 124D.

Done! I just ordered it from Radio Daze. As well, just picked up a make of radio I usually stay away from. I low bid offered a guy for a 1935 Grunow All Wave tombstone. Bought it this evening. Got my fingers crossed. The last Grunow I worked on was a huge Tele-Dial console way back in the 90's and it never worked right. We'll see...
