They most certainly are not. They are proportional to the difference between the input voltages and nothing else, or to the single input voltage in a feedback arrangement, until the output level hits the rail voltage or thereabouts, when it clips.

I breadboarded some of the pre-amp's and all the output chipamps, but notthe whole thing together. So now with it soldered up it's sort of a pain to fix stuff.

1 thing I should try also, is with the 7806 on a breadboard, take some single-shots of the start up, see what's actually happening. I can current limit my PSU so overall nothing gets too toasty.
