A Story of Two Bellies …

This is a story of two bellies …

… or a story of an S3 grid which is **NOT** internally connected to the cathode,

S3 - NFB

This is the Twin Belly Topology, … (C) 2014-10-17, zjj_wwa, of hiend-audio.com

One “Transconductance Belly” is facing down.
The other “Transconductance Belly” is facing up.

But what happens when we multiply
the “belly down” transconductance by the “belly-up” transconductance?

Envision the operating points at say,
U_a = 1500V,
U_s1 = ( -140V DC + Signal_AC),
U_S2 = 600v = Constans,
U_s3 = ( -140V – Signal_AC).

My question to you:  Belly_Up   x   Bellly_Down  =  Straight Wire With Gain ?
