Hi all out there.
I found a transformer in my basement. I don't know if its a audio-output transformer or just a power transformer.
On top it's stamped "GALVIN MANUFACTURING CORPORATION",
and a model #: "25B31296-E" and a serial# ( ???? ) "138226"
At bottom there is 8 solder lugs, stamped: "1 to 8".
And at one side is 8 screw connector, labeled as "3A 12 11 2B 2A 10 1A 9".

To me it looks more like a tube output transformator, more than a power transformer.
It seems to be from the 1940 or somewhere around there.

Anyone know what it is, and have some kind of "schematic" of the transformer.

Many thanks in advance
