2017 Sony VFET PCBs
What are these?
These PCBS have nothing to do with the 2021 DIY Sony VFET offering.
This is a re-release of the 2017 Sony VFET Kit PCBs from our 2017 Sony VFET kit. You can read about this amplifier design in the Sony VFET Part 2 thread. This was a very special kit because the VFETs (transistors) it uses are not made anymore, nor available for purchase.
These boards play well with the TO-3 brackets (currently unavailable).
WARNING: DO NOT BUY THESE PCBS BEFORE YOU HAVE TESTED, GENUINE VFETS PHYSICALLY IN YOUR POSSESSION. GENUINE VFETS ARE ALMOST IMPOSSIBLE TO FIND.
Why have we re-released these boards?
We have infrequently received requests from people for these boards. Typically these requests are from people who happen to be lucky enough to already possess the VFETs.
Where can I buy VFETs from?
The short answer is that you can't. Almost all VFETs you will find available for purchase online will be fake. You might like to try the diyAudio swap meet, however there are no guarantees and you might get ripped off. Buyer beware.
