Hi guys!
Just recently someone has posted a link to a website which had some nice explanations of how to calculate the resistor values for a common source J-Fet amplifier.
It definitely wasn't from the geofex, that's all I remember. And I hasn't bookmarked it. Anyone may have seen one? It has calculations for bias and current, etc...
I know that probably 50 websites out there that fit this description, but anything goes! :D Thanks in advance!

A.S.P.

Yep! That's it! Thanks a bunch! :D
Not to get a J201 which can be fed with 40VDC and off I go with a preamp for my LM3886! :)
