Nice ! Sony soon to start a brand new V-FET production line... 😀

 

[NYCOne]

Any chance they'll let folks buy the VFETs directly?

😀 Ok now we know why you built the monster.

Fantastic news....ofcourse it won't be easy for DIYers to get them.

Has it already went off?! There are two caps missing on the input board! 🙂 joking, it looks amazing! I would say internal layout reminds me more FW amps 🙂

I have a great respect for a layout like that. Much more difficult than most realize. Almost as nice as the circuit, I am sure. SE only?

The caps are too tall for the top of the board, so they are mounted "upside
down"

Wow, those are really gorgeous! I hope they come to Northeast Ohio. 🙂

It's been awhile now since TO-3s were in a new Pass amp...beautiful! Mr. Pass, did Sony commission you to build these or you just have a lot of Sony SITs in storage needing a special project?

 

[flocchini]

Absolutely outrageous. Congratulations Nelson

Crazy =)

How do you solve biasing, are they all super matched so you can use one bias supply per side?

And on the topic on supply, do you know if they will manufacture more VFETs, possibly new modern ones?
