Peerless mystery transformers

[jmarkwart]

Hi All,
I was clearing out a closet in my workroom and came across a Peerless power and output transformer set that I can't identify. Power is #6473 and the pair of outputs are #16517. I looked through my Altec tube output circuit schematics but couldn't match the numbers. Anybody here know? The outputs only have end bells on one side, so they probably laid down in a "low profile" chassis.

Hi there:
If you have access to an audio generator and a scope, you can easily measure the primary impedance of your output transformers.
