Thanks.Code:
.MODEL ksc3503 NPN
I simulated the circuit using your model of ksc3503, which you posted in #38.
Success!
Now it even works with overdrive/clipping. no latchup
Seems that the model of ksc3503 that one can find on LTwiki is not quite right.
I'll call your model ksc3503_2 to distinguish it from the 'wrong' one.

try the kinda-blameless_2.asc file from post #41, this should work.My simulations (based on the .asc file added by catd) are still bad even with the values from the last post#37
or try this one
kinda-blameless_3.asc

Both work well!ry the kinda-blameless_2.asc file from post #41, this should work.
or try this one
Thanks!
Now I am in the process of assembling the CelloOne amplifier (from another topic of the lineup)
Maybe this one will be next? Who knows?
That is alright.Thanks.

I see you have added some compensation.
Between the LTP pair.
Also adjusted the TMC comp.
But if it works it is alright.
I like the fact that you build my amplifiers.Both work well!
Thanks!

I can hardly believe someone likes my stuff
Hi...
In case I wanted to build this thing, I searched the net for the Exicons (10N20/10P20).
They are not easy to get and then not cheap either.
That's why I tried other Mosfets, which on the one hand are included in the LTSpice database
and on the other hand can also be purchased cheaply from my preferred supplier.
The result was IRFP240/9240.
At least in the simulation below it works with them.

I dont think that is expensive.
For using IRFP240/9240 I believe we need a VBEMultiplier in VAS.
Laterals like ECX10N20 are easy to drive, but IRFP240 is not so easy.
And there is the temperature that a VBEMultiplier takes care of. HEXFET can runaway when heated.
But if you try IRFP240 it might be good. I really dont know.
Best is of course the lateral ECX10N20.

That is of course better than IRFP240/9240.I will try 2SK1058/2SJ162
Because it is Laterals.
