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

Thank You all for the reply.
I understand that there would be easier if I could present a picture of the transfprmer. I have pics, but I don't know how to present them here in this group.
I did some measuring with my L-meter, so I now know where the coils are.
I'm pretty new to this group. Please tell me if I can present a picture right here in these group. Or can I present a link to eg. One Drive or DropBox or similar....
