I have a PPI PC2150 it seems to work fine but when using a test cd there's a 2.4V difference in output at the speaker terminals between left and right. I have another just like it and the diff is less than 1V. I adjusted both to put out 34V @1khz-0db bridged and when I looked at the gains they were in exactly the same spot on both amps. What is the normal variation in 2-channel amps using a single gain? All testing was done at the same volume position using a Clarion deck and i also tried switching the RCA's around to be sure the input voltage was the same and got the same results.
This may seem a bit misleading, but tolerance is usually +-5% for resistors and +-3dB for potentiometers.
Note that +-3dB is approx +-30% error between channels.
