Thanks Patrick!
I know I can always get my head on straight aftert reading your post.
I have a MJE340 set up on the bench and it is solid as a rock.
I had noticed that ARC used FET's and thought I might be missing something
there.
If you examine the circuit of the ARC SP11 preamp from around 1987,
you will see how not to build a simple preamp IMHO because the sheer
number of devices and bits and pieces and loops of high amounts of NFB
are mind boggling.
But the amp measures well; it measures astonishingly well for
single ended triodes all hooked up one after the other.
But just as good sound, or perhaps better sound many would say can be had from
circuitry with 1/3 of the parts count.
I still want to try the FET and make some test befor I commit to a PCB.
Thanks Again

Allen Wright likes fets used for CCS, i suggest you take a wander around
his site at
http://www.vacuumstate.com
He may not agree with an MJE340 for a preamp,
maybe because there are lower noise fets which suit his preamps.
Erno Borbelly also says a few words on fets....
