Well, I think in Digi's part of the world there may be a practice of referring to common JFETs as FET's. Whereas a MOSFET is rarely referred to as anything other than a MOSFET.

You are certainly correct about confusing.

But (as writed before) when look in PCB ver.3 :
in config "LND150 MOSFET CCS" when we switch jumper we switch C2 to pin G not to pin S.
We must make changes as writed before...

Yep. Mine too.

In fact, I'm the reason that the mu-follower configuration was developed. Had some wonky opamps I wanted to try so Runeight provided the answer after I was getting huge amounts of offset.

With the mu-follower config, can I use LM6172? Would it be too cranky for unity gain?
