hey has anyone moded a behringer tube ultra gain or tube mic200 here?
and on the tube mic200, i was wondering if 12aX7a tube on the pcb can be used in some type of hybrid. the tube is on a little pcb w/ a few caps and what looks like a voltage regulator. how easy would it be to intigrate it with say an op-amp headphone project?
