Untested but excellent condition transformer. I do not claim to know how this transformer should be utilized in your particular circuit – pics are of the actual transformer you will receive – specs for the transformer are in the pictures. If you have any questions or I can help in any way don’t hesitate to ask. Listing price is for 1 transformer.

I believe it’s a tube amplifier. See all photos for condition and what’s all included.
