I am aware that you could not get 36v+ with a rail of only 36, but i have run these line of amps many times in the past, and i could have swore that they were 200mv sensitive. I was expecting 32-34v by 250mv at max gain.

I do not understand what you are implying. It sounds like you are saying that rail sag does not exist without severe clipping

It's not possible to get more than ~25v AC without clipping the output with 36v rails.

When you read less than 10v with the amp loaded (200mv in), what was the DC voltage across the amp's power/ground terminals and what was the rail voltage.
