kasey197, who is "acorn man"? I want to buy some backups for my SIT amps.
Thanks!
Vince
Yes but they are REALLY linear
laftets jfets mosfets bjts etcetc are in a lower class of linearity altogether !
I didn't meant on Pass SIT-1 & his (unfortunately just) hypothetical brother ;
I meant on whatever complementary output parts used ....... we see that only needed biasing voltage is different for different parts
so , starting schematic is piece of cake , already shown (in principle) in thread
pair of input jfets , repeater , few TL431 ( as probably in last iteration of Pa's F6) for bias nets , few mosfets/Sony Vfets , few caps and resistors......... and you have enough parts for 2 moths of tweaking, measuring and listening ....... to decide what could be final version

even Nelson asks how does it sound.....
