>The higher ohm side that goes to the 6J5's is 215 ohms/200 ohms. Only the 200 ohm section is dead. The other side links to the input grids on the 6F6's. That side is 38 ohms and 34 ohms. >

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.
