When powering on my amp, both gains turned fully CCW the right channel LED is initially at the far left. Once the relay engages the right channel LED light jumps to approx 60% of the scale and stays there. When I turn the gain knob it appears the LED light moves up on the scale but only after turning the knob approx halfway up. I have interchanged the chips from left to right channel with similar results and do not see any burned traces. I have interchanged the 3 LED chips also with no change. Any ideas are appreciated.
