Really cool projects (this and jcm800)
The only thing that worries me is it's costs.
Looks like at such high voltage these projects could cost close to real tube versions...

Dear KMG, I must congratulate you on your impressive work.  :tu:

But the sound is also close to tube prototypes, especially while live playing. The main advantage of fet versions is their reliability & long time sound stability (no effect of emission loss).
During the "blind" tests guitarists usually say "I can`t tell what is the specific amplifier, but certainly, tube one".

Yep, this is how I read these two projects. Lot's of care and testing resulting in a design that's a very close (or better) match for tube characteristics, but with all the durability benefits that come with solid state. It should sound the same from day one until the electrolytic caps leak (figure twenty years with good caps), barring damage or bad luck with one of the semiconductors. The FETs won't age, degrade (enough to matter), and require replacement like tubes would. Definitely an advanced project, but a real masterpiece.

I was also wondering if KMG would be so nice and post some more info about winding those nice output trafos for his FET power amps...

Excellent clip as always KMG, sounds great.  What type of guitar and pickups were used in this recording?
