Its phase shift that does that, and phase shift mostly happens in iron I
think.
It sure sounds like one transformer is bad...

That is a possibility Dennis however there is little if any difference in the
open loop gain of the two circuits or their output level before clipping about
(40 watts). I was thinking that perhaps the primary wires were color coded
incorrectly, as I am nearly positive they are, and the secondary
It sounds like you may have a shorted turn in one of them, NOS
notwithstanding. It has happened to me, and it forms a tuned circuit
resulting in a phase shift as it is an LC network now.

This is maybe a little off subject here but I ran across an interesting thing.
It may be of interest for someone building higher quality speech amplifiers of
modulators for AM.
While constructing two identical amplifier circuits with inverse feed back for
a stereo operation, I discovered that
