Hammond transformers
I do not know the model number or the value, but it is big and heavy. It weighs 14.45 lbs if that is any clue, and it could be a 193P. I think it is at least 5 Henries inductance. Whatever the model number is, it was used in a guitar amp with 2 EL34 outputs, so it is heavy duty.
