This listing is for (2) Motiograph MA-2637 power transformers removed from a pair of modified Motiograph MA-7515-A Tube Amplifiers. They were working amplifiers.  The original tube compliment of each amp was (1) 5U4G (1) 6K6 (2) 6SJ7 (2) 6L6.  These transformers both have MA-2637 and 606407 stamped on them.  (I am not certain so do your own research, however, the MA-7515-A amp appeared to be the same or very similar to the MA-7505 amp. I do not know what the difference was.)  The ohm readings are shown on the last photo.

I gladly respond with feedback for buyers who leave positive feedback.
