Thanks for all the help
JasonL,
It is Circuitmaker student edition- freeware, but limited to 50 components. Seems easy to use. I can't remember the address- try searching google.
I will try to exaggerate the effect when I get home tonight(I don't have the circuit on this computer). In it's worst form, it was the waveform plus a smaller double hump on the trailing edges. The only thing I can think of is that there is something asymmetrical as far as impedances go with the input and the feedback arrangement. There is no attempt to make the input impedances equal in this circuit, as it will be completely symmetrical when it is finished (alephX). That may be the whole problem. I hope that this is worked out when I add the other half of the output stage, and use the X feedback arrangement. It would be nice to know that it works before I go and build it, if you know what I mean. I know that it is swinging close to the rails right now. Maybe that is some of the problem. At least with this attempt I have been able to test the Aleph current source and adjust the AC current through the feedback resistors, etc. as in Zen Variations Part 2. That was my goal anyway. I guess I just started to worry when I didn't get a nice looking waveform. Anyway, I would like to know what is causing the problem, in case I end up building an Aleph someday. Also, just for the sake of learning something. I appreciate all the help... please keep the suggestions coming.
