Help finding data on vintage Peerless Transformers

Hello,

First post here, but regular reader ;)

i got a set of 2 x input and 2 x output transformers that i pulled from a working Westrex cinema PA tube amp ( it was impossible to keep it and restore it... ).

They seem to be Peerless / Altec Lansing corp. Transformers, with references : T-101, T-102.

i already looked in the Peerless catalogs of 1960, 1953 and 1950 that are on the net, the references doesn't match, but at least they fit the "Q" type enclosure

If anyone has infos or know who to call / e-mail, where to post ?

Thanks !

No...
i mean, i have to check the photos from it ( 10 years ago ) but at the time, i did extensive research with what i had, and didn't find any relation / model...
i don't remember any serial n° or else.
I'll check.

The Westrex amp was mounted with point to point hardwire inside a 1m / 3ft high steel rack
 
What tubes were used with it? That will give an idea of the power rating and impedance. Impedance ratio can be measured easily, power rating takes a bit more.
 
and here is a set of measurements from the transformers made by a friend who is repairing / making guitar tube amp, which currently have them @ his home !

Those are probably OEM numbers: part number specific to a particular customer, in this case Westrex. There is a good possibility that the OEM part numbers correspond to an standard Peerless part number. In the end you need to measure the turns ratios primary to secondary to figure out how to use them. It looks as if your friend might have done, this but I am having difficulty is deciphering his notes.
 
Thanks,

in the 3 catalogs i looked at, there is no corresponding ref in the input / output section.

i reviewed all schematics at : https://www.westernelectric.com/archived-amplifier-specs.html
the westrex A10 amp and A11 amps have T120 ( input ) and T121 ( output ) refs.
all transformers have refs number upper than 120, even designs that where created in the 30's...
the original amp looked a lot like their model 100 and 101, but half smaller
