The JH636 is a nice desk.

I am using this Bi-amp for a live venue at my ranch where just last yr they installed a 50KW FM station just up the road. The transformer coupled mic pre-amps were dead quiet where every other desk I could hear 97.5 FM on some inputs using AKG 535s and other condensors.

I have two pots apart. If I can swap the shafts I'll be set. Otherwise, its gonna have an odd knob on the last chan.
