Westinghouse WR-258 Power Transformer Replacement
#1

Acquired a Westinghouse WR-258 radio that looks like it will need a new power transformer.  Found a large pool of black wax under the chassis and when I opened the clam shells it's apparent that the unit was severely overheated at some point in the past. Both the primary and secondary sides showed continuity, but it really looks toasted. I've repaired a few radios in the past, but never had to replace a transformer. 
 
I've found a couple of Hammond replacements, but not sure which would be the best fit as they don't match exactly.  I've included the specs for the current transformer and a couple of available replacements.  Any advice on a suitable replacement model would be greatly appreciated.
 
Since I couldn't locate the specs for the original Westinghouse power transformer, I looked up the replacement using a Thordarson catalog and found the following model listed:

T-22R00: 117v/50-60Hz, Plate 500v CT @ 40ma, 5v @ 2a, 6.3v @ 2.0a
 
Hammond 270X: 115v/60Hz, 480V C.T. @ 46ma., 5V @ 2A, 6.3V @ 1.5A
Hammond 270CAX: 117v/50-60Hz, 500V C.T. @ 81ma., 5V @ 2A, 6.3V @ 2.5A


Here are the schematics for the WR-258
