vssa squarewave response

[ctrlx]

How about this: just build the darn thing...

i'm in no hurry....if i decide to build it has to be worthwhile to do so. implimenting a baker clamp


thanks to DIYaudio members, i can make much more assessment with sims and the real circuit before committing to a new build.

I don't know why the maximum Zobel capacitance for a good square wave response dropped from 10 nF...22 nF to 1 nF in later posts.

i repeated those tests, but zoomed in with the scope, to reveal more detail.

MarcelvdG, i have done some stability tests, using a 10KHz square output at 0.4Vpp.
with no input filter and no zobel, i got the amp to oscillate with a cap of 1nF
the oscillation can be stopped with the use of the input filter 220p, or the zobel 1n/10R or a 0.8uH output inductor.
