I breadboarded the 'first generation' jfet opamp from the forssell site and it sounded great and I was able to adjust dc offset to almost 0mv with the trimpot. I made a PCB and now in the same circuit I cannot trim the offset to less the +50 mV. It works and sounds OK but I can't seem to solve this. I have matched the Idss of the fets and even swapped out every Fet and resistor on the board. What am I missing?
Thanks, JEfff
