Hi Al,
I wasn't aware that the MC 275 amplifier relied on generous use of negative feedback (NFB) in its circuit. This is an obvious example of influential variables I had mentioned earlier. I once used a push pull amplifier that had adjustable settings for NFB. You could alter your preference for choice of cables or tube rolling based on which NFB amount /setting was chosen.
