Default A personal nostalgy trip, my old amp

I spent sunday afternoon cleaning the harddrive from oooold stuff that should have been sorted a long time ago, and I found my old hybrid amp, had olmost forgotten how awful it looked, hmm not sure where to post hybrids but it uses way more solid states than tubes so here it goes..

Starting to get my shieat together..

And last but not least the schematic which I'm not really sure works very good.. the irf640's were replaced by some irfp stuff, and stability was somehow found..

The output follower push-pull is very similar to Nelson Pass F4.
But you have considerably higher voltage (+-60 vs. +-22) and Nelson uses IRFP240/IRFP9240.
