Is it necessay to connect both case bolts electrically?
I'm thinking this may create some undesired effect (not sure though).

While i admire immensely your aesthetic talent....and would like this amp to be look so special as it is ...please listen to ZM ...and read EUVL's paper on heat-sink heat distribution.
If you can combine all this with a truly unique and gorgeous design ...man you are the man. !😀😀😀
Actually Euvls paper is based on some lab work I did for him. Except I mapped the entire heatsink through laboratory measurement.
He then came up with a way to mathematically model it.
So yeah as it has been said repeatedly, it is best to space mosfets further apart for best efficient use of heatsink.

That is certainly looking good.
PCB layout ..can you post ? ( i mean the 2D version...)
😀
It look very good now....i don't see a reason why there should be no interest...
I centainly am interested....and no i am not from Ethiopia...i knew you could...but would you ? 😀

Just received 2 x 2SK82 from Ebay seller "polida2008" and I'm sorry to say, fakes again.
They look exactly like yours with good JA-33 printing, but when flipped the G and S is opposite.
Put a drop of Isopropylalcohol on them and you wipe off the text completely 😡
Then I measured them and yes, relabeled 2SK60s again.
I stop here, no more VFET's from Alibaba or Ebay for me.
isn't 2sk60 a vfet as well? So if it works, it can be used in a different design?
Sure 2SK60 is a VFET. And it can most probably be used in the VFET part 2 design because it's used as a follower. But I don't like to mix up two different type of transistors in one output stage. Basically 2 x 2SK60 = around 1 x 2SK82.
you are not as greedy as me, I bought 4pairs which cant be returned. Well if it's 2SK60 then at least it can be used someday, who knows Papa will release another vfet version
