You can play a 60Hz tone into the inputs of your amp, then measure the AC voltages at the speaker posts (you can leave the speakers hooked up) at a normal listening level to see if the outputs are playing at the same level or if you're correcting for some other imbalance that isn't electrical.

OK, I’ll try this and report back. Thanks.

As a general rule pot tend to track better at higher settings. Do you notice this?

Something you can try, with the amp switched off compare the resistance from one channel to the other at a few different pot settings. You would be looking for significant difference in one channel at a few settings..John

Sam, you can experiment with the technique that PB recommended.  I do this for setting up my system.  Try it a different volumes. Put on something that you enjoy to listen to at a low volume, then switch to the 60Hz tone and measure the voltage.  Move on to music that you like at higher volumes and repeat.  This will help to set you preferred listening levels.
