(p)resume that SIT is more linear , and that R100 is tamed with source resistors

R100 is output?
Certainly a fair number of Pana Resistors in play here.

[Zen Mod]

well - last time I looked , Mu/SRPP/whatever need two active parts to be complete

Papa:

The amplifier circuit has a single stage consisting of the SIT biased by a Jfet set up as a mu follower

that can be anything ..... SIT on top , SIT down .... really depending of fact from which side you're looking

[buzzforb]

Mu follower suggest drive transistor with current source. R100 on top makes for better current source, acting like pentode, increasing impedance and allowing full gain of bottom SIT to be used if so desired. SRPP would have SIT on top and bottom, hopefully receiving as balanced a signal as possible and acting more like quasi push/pull. All this is speculation. I don't really know, but trying to figure out.

[Zen Mod]

we are , anyway , in bird's milk territory ........

[Nelson Pass]

Since you are speculating, the current source is not constant. It has
a small amount of compliance, on the order of a hundred ohms, which
makes its load-line participation small.

[generg]

The R100 is on the top, red cable +voltage, and the SIT is in the lower part, input cable....look at the picture.

[buzzforb]

You are correct. Now its time to try to clone with R085.

good ;

observing vocabulary in last few paragraphs , Srajan is on his own , again .
