No, they are not Hammond's, they would be a American made brand and it's brain fade right now that stops me from pulling the manufacturer out of my head!
There is a 6 digit string of numbers stamped into there case, what is the first 3 digits?
Here's a short list .
138 stanco
238. Thordarsen
830 triad
Oh, and a gs 12 is lucky to make 30 watts of peak power with the original 7591 tubes, so do expect the punch the amps would have had with 6v6 tubes!

When I die, I want to go like my Grandfather did, peacefully in his sleep.

Ampeg used Electrical Windings but that's not to say they didn't use other transformers also. Ampeg was famous for changing circuits and also famous for sourcing parts from many different vendors.
the numbers are
682-539 on both pt and ot.

Electrical Windings, now known as TMI (Transformer Manufacturers Inc.). Made in the 39th week of 1965.
