You sorry ***. Ill be all over you when I get the comps. I have some ideas of a dualcase double mono. Anything against that I wash you over with CADs?
Q1,4, and 7 are bootstrapped CS, correct? What is Q2,3 and Q5,6. THey are load for input Jfet, but whats going on with how they are connected to input
Q1+M3 are CCS (lokielookie at Aleph series , up , nada Aleph in CCS) , forming tail for M1&M2 LTP
going from left side :
J1 is part of input buffer , mimicking Tectronix/later Wright SLCF* , which is basically follower element , having cascode on top (Q4 , biased through R36/R37 where C4 is bootstrapping cascode potential to J1 source ; if you introduce Rs there , you'll have small amount of Papa's sweetspotting , known as one of cascode modulation variants ....... yukyuk , while it (follower element - J1) is loaded with own CCS , formed by Q2&Q3
- same on other side
R29 is formed , in fact , with series connection of 47K fixed resistor and 47K trimpot , giving you possibility to setr desired Iq through main LTP ; my goal was 4A , meaning 2A through each LTP side
if yo have slight mismatch between two halves current(s) , I wrote that already , just introduce small trimpot in source of input Jfet ( either J1 or J2 ) , on side which is having greater current
simple , isn't it
*SLCF - means Super Linear Cathode Follower , meaning - nasty triodsess working in constant voltage mode , loaded with CCS , so being able to both pump and suck current ; change nasty triodsess to whatever makes your heart warm
edit :
DC set/points
again from left side :
J1 is having gate fixed on GND potential ; while having current biased with Q2+Q3 CCS , source of J1 is finding his own place in voltage universe .......... fixing on same spot gate potential of M1 ......... which is current biased with Q1+M3 CCS , so source of M1 is finding his own place in voltage universe

F5 is for sissies ....... so I never had opportunity to see that you , actually , replied
please - do not ask for Ultrasymmetry instead of Super one
catch is double , so 22 ; we are lacking some gain to spend , and Ultrasymmetry isn't recognized in this (and neighboring) Universe(s)

clumsy ZM .........
....... forgot one (two) important thing
twice 4u7; C6 & C9
2u2 to 4u7 is good

Netlist?
ZM...... great effort.....
Would you happen to have a Spice Netlist you'd be willing to share with us all?
Possible conflict of interest being formed here..... Can you give yourself a "fugly" for a nice amp design???

whazzup sissies ?
not yet finished one ?
Sleeping beauty just woke up. You've been busy changing the values I see. Thats why I made the bom, cause I lack pretty much everything besides resistors. What value are you counting at for the SK170s, is it BLs?
O.H Schade. R43/44? A friend Lars boggled about this a while ago.

whatever ...... preferably BL or V ......... their current is in range of 8-9mA there ; buy 100pcs of J309 (J310) and enjoy
yup , that Shade ; covered here in Papaland
for which one ?
or both ?
( as soon I see how to make netlist )
