This is from a Brazillian designer who reckons his designs are the best (a South American Nelson Pass) Seems to work OK and I have modified the schematic now by reading deeper into this thread on DIY Audio

his designs are OK but his hearing sucks

220nF at input is much to big. I guess its 220pF. BTW, were is the load?

I put the load but if you mess with the 220nF it becomes unajustable and gives high dc offset

Set it to 220pF and restart simulation!!!!! Have you checked the original schematic? Btw, this amp is completely unaligned. And why do you hide the load behind 1kOhm?

I tried the 220pF and that upset everything and made the O/P clip however a later diagram corrected the cap to a 220pF and heres a oink to that - http://www.diyaudio.com/forums/solid-state/96237-destroyer-x-amplifier-dx-amp-my-amplifier-3.html

Now modified, the latest circuit however does not fit on the tiny EC design area

Phildela, then you realize something here. You can just move your circuits on the right and there it is! More spaces to work on your circuit on left side.... seriously have a banana....

The work area can not be increased - can it? Components can only fit in the allocated space and often they cant be placed too close together. Is there a trick I am missing? I had a banana but it didnt help!
