Ok, this is bearable, but just noticeable to drive me nuts.

I've A-B'ed both channels, swapping out everything~ cables, tubes, power amp channels, stereo, mono, etc etc… and it's something in the actual circuit. Ch1 is always about 1.5db louder than Ch2. I have yet to take a meter to it, so any help as to where to start, and maybe what voltages I should be seeing would be great!!!!

P.S., the only components that look like they're from two different batches are the Midrange 10K pots.

Have you tried raising or lowering the pickup height?

Thanks Slawie, because the end result that I'm hoping for is to run my series instruments through the rig w/out any differentiation between the two channels..... but I haven't gotten there yet..... For now I'm running all my mono guitars into an A/B box going to each channel of the F-2B. Even if I jumper a mono instrument from ch1 to ch2 , ch1 is still louder.

So in a nutshell, no, I haven't adjusted p/up height, because my series instruments haven't factored into the equation yet....
