Volume imbalance

When I adjust my dual volume control I can almost never seem to get each channel to equal out.  I can adjust one side but then it's just a little bit louder than the other. I believe it's the nature of the tolerances of the stepped Alps pots. I've got room for the Khozmo controls. But I'm not sure if this the way to go. I'm looking for opinions/experiences or suggestions. Thanks for any help. Would an audio taper pot be ok?

I looks like they've done something pretty shifty with wiring on these, as you have separate left and right pots, yet that no (100KAx2) indicates they are both dual gang pots.

Also this unit is getting very old now, and due for pot replacement, seeing they are cheap replace both, if your up to it.

Appreciate the help, I think I am up for it. I wonder why Mike Sanders would put dual gang in them? I thought it was a mod someone did along the way to my unit.

The Single most important component in a preamplifier if not going with a stepped attenuator go with as high quality potentiometer as you can afford - the TKD IMO is superior to any Alps one - here is a 100K Audio taper one

I agree with Peter. I have found the TKD controls to be excellent.
