I talked with Edmond who designed Diana by PM.
Very nice guy!
I succeeded to see the residual of my DEFSIT as well of other amps in a similar way I could do it with Lynn's Octave program.
So both software and ideas run in a way parallel, that is very nice.

I looked really for many years for this residual possibility, I even asked Nelson.....I suppose he does it in the hardware way.

I asked Edmond, if Diana can show the residual in realtime, while for instance, turning the bias up or down.
He answered that he intends to implement in the free version of Diana, in a short time, a repetion mode that shows after calculating for instance 100mseconds the resulting residual.
So a kind of semi real time!
Fantastic!

Where can I find the BD140 Spice model. I have an interesting change to that circuit, but I need to run the simulation first.

In your Simpler_Spook.asc file, you should really change the name from 2SK170 to SIT-1 or something.
Click to expand...
BD 140 is in LTSpice standard.bjt library, I copy for you here.
Code: 
.MODEL BD140 PNP ( IS=2.9537E-13 BF=201.4 NF=1.0 BR=23.765 NR=1.021 ISE=1.8002E-13 NE=1.5 ISC=7.0433p NC=1.38 VAF=137.0 VAR=8.41 IKF=1.0993 IKR=0.10 RB=1.98 RBM=0.01 IRB=0.011 RE=0.1109 RC=0.01 CJE=2.1982E-10 VJE=0.7211 MJE=0.3685 FC=0.5 CJC=6.8291E-11 VJC=0.5499 MJC=0.3668 XCJC=0.5287 XTB=1.4883 EG=1.2343 XTI=3.0 Vceo=80 Icrating=3 mfg=fairchild)
.MODEL BD139 NPN ( IS=2.3985E-13 BF=244.9 NF=1.0 BR=78.11 NR=1.007 ISE=1.0471E-14 NE=1.2 ISC=1.9314E-11 NC=1.45 VAF=98.5 VAR=7.46 IKF=1.1863 IKR=0.1445 RB=2.14 RBM=0.001 IRB=0.031 RE=0.0832 RC=0.01 CJE=2.92702E-10 VJE=0.67412 MJE=0.3300 FC=0.5 CJC=4.8831E-11 VJC=0.5258 MJC=0.3928 XCJC=0.5287 XTB=1.1398 EG=1.2105 XTI=3.0 Vceo=80 Icrating=3 mfg=fairchild)

I use 2SK180 model from Mr. MR, not 2SK170.

anyway , worth noting that in spooky - current distribution between outputs is sorta conventional - both are contributing to output current in mostly unison way , as any decent A class stage need to work

though , I'm lately hypnotized with Papa's ∀ Class , even if unintentionally invented :rofl:
