Output Transformers: 95-1633 and 95-1657 Compatability

[Harlon]

I've got a line on a pair of PP OPTs that were used with pairs of EL84's. They were both RCA amps but different configurations. One integrated, one not. They are stamped 95-1633 and 95-1657. Can anyone help id'ing these OPTs. If they're "close" enough I want to try and use them to make a pair of monoblocks.
Sorry, no pics.

If you can confirm that they weigh the same, have the same leads, and have the same primary side resistance values, then it's likely that they're very close in other characteristics as well. I'm guessing that the seller may be able to provide this minimal information even if he's a tube audio ignoramus. There are other useful tests, in case the guy is more capable.

+1... A Turns Ratio test will confirm what your asking...

Happen to have schematics or model numbers of this amp? That would probably give a fair clue as to how different they might be.

Those look like Zenith part numbers ("95-xxxx"). Late '50s to early '60s. In fact, I found a Zenith part number below those in a '59 Sams folder, and a number above those in a '60 folder. If you can find a model number, I probably have a schematic, .
