Thanks for every ones input, broken ground at speaker terminal was the problem.
I should have checked the easy stuff first.
Lew you were right.......
I was able to compare input sine wave to out put sign wave.
I learned a lot.
I am wondering.
If I input 5k sine wave to both channels,
and adjust bias voltages so they are equal, and then compare
magnitude of both channels with o-scope and adjust bias to output
signal rather than bias voltage for a truly balanced L&R signal.
thoughts?
tweak I must!....
