Half the VSSA works well, too.
A little bit more THD(0.007% at 1 Watt), but it behaves well even at higher power output.
I almost forgot to thank you lineup for this experiment. So even half the VSSA is working good, that means the whole VSSA is good to go guys hehe.

Hi LC, these one could do the job : ALF16N16K/ALF16P16K. Here are the datasheet : http://products.semelab-tt.com/pdf/m...0ALF16P20K.pdf

Or this ALF08NP20V5 double n+p channel mosfet in one TO-247-5L case? Just perfect for VSSA.

I see it like this - just because somebody starts a thread doesn't mean they made any clever inventions at all, they just took the initiative to start a discussion. For sure this thread has for me, nothing much original, but it generates some interest and some discussion. I guess some people just like to have their own thread, to do things their way. Carlos the Destroyer being a famous example of that ! - and perhaps true also for Lazy Cat. I agree it could have been made clearer by Lazy Cat.

Look at Pass Labs - you see a lot of old stuff regurgitated and people refer to it as 'Pass design X' when it was somebody else who first showed this topology. F5 is a great example and Nelson also acknowledged that somebody else was selling the same design already before him. There are not so many ways to put things together and they get re-invented over and over. Even the topology that is the subject of this thread was not originally from Gabor and that was said also in that thread.

I hope Gabor continues to develop and build that version, I will be following it too.

Well said Bigun, as I am not native in English, it would took me ages to tell exactly the same story. Thanks

If doing the things "your own way" is to make carbon copy of amps and
saying that it s different , yet keeping mum about theses "differences"
and then opening a thread to propose a non mature design (it has been
discussed in many threads) that will be a hassle for beginners , why not ,
since for some it s a raison d etre....
