How to calibrate Summit Audio EQP 200-A?

Does anyone know how to calibrate a Summit Audio EQP 200-A? I need to align the L/R channels - they're about .4dB off from each other across the whole frequency spectrum (which probably rules out a tube going bad).

Looking through the top cover, I do see a couple of potentiometers labeled R22 and R72. It's possible those are the I/O adjustments. They could also be bias adjustments

It seems like it would be a very simple adjustment. I reached out to Summit Audio but haven't heard back... maybe they're not around much during COVID.

Any help or direction pointing greatly appreciated!
