2252B "weaker" right channel

I recapped my 2252B about 2 years ago. The right channel has always been a little weaker than the left. Now I'm using the 2252B as a pre/tuner for my Dynaco ST400 amp and the right side is still weaker even when using the Pre Out of the Marantz. By "weaker", I mean that the left channel sounds much more rich and full. Volume is not so much an issue. I've swapped speakers, de-oxit on the controls, all that stuff.
Basically, where should I start looking? Perhaps semi-conductors on the pre board? Main transistors? I don't know where to start. I have the service manual.
Thanks,
Jim

I would normally suggest the caps but they have been done. Then a sticking loudness switch came to mind but you've cleaned them and I assume recently. It may be time to seek a tech to take a look at it.
