Here you zie at the end that for the decimal he uses a , ( comma ) but this should be a . ( point )

Maybe this is a program fault becouse my windows is set on dutch
Yes, I believe this is the case, you can of course change the default European "," decimal point to "." in Excel.

OK, it's not a vacuum tube -- perhaps we can convince the folks at PEAK to allow use of their GUI -- this is a curve of the LU1014 Power JFET, gm is about 80mS

Why do you feed the 12ax7 with the anode line of the 6ca7 this should be better this can give to mutch feed back.

And next time you post a ASC files also iclude the the lib or inc files

my target was full power at ~2Vpp input, like from most cd playres, or other sources,
besides it is not too much nfb untill the device not oscillates
this configuration gives euphinic sound end extraordinary deep of the soundstage.
this is link for real built amp: http://www.diyaudio.com/forums/tubes...tml#post898445

I see that those files are not realy used bij the sim so why do you have them as Included in the sim???

And why simulate on 20000 Hertz these freq is usaly not the problem 30 Hertz or lower is.

I have standard directives for the simulations and I copied them for simulations, yes cordell-models.txt is not necessary.
20kHz is for the same reasons, you can easy change it to any frequency you want.
30Hz sim is not bad too.
