DIY Sony VFET pt 1

[Nelson Pass]

Now is the winter of our discontent made glorious summer by sunny skies
and celebration of my 20 years on this forum, not to mention recent
vaccinations...

I present the DIY Sony VFET pt 1, detailing the design for the P channel
amplifier version using up the last of the Sony 2SJ28 VFETs, to be followed
by part 2, using up the 2SK82's.

diyAudio will be offering a limited quantity of complete kits of both versions,
so watch for the announcement in the store.

Later there will also be offerings for those who have these and the other
Sony VFETs already, and also other FET devices.

Wow. I can’t believe the first 100 sold out in under 5 minutes! When will the next wave be up on the store site?

This is wonderful. Thank you as always for putting such thought into the articles. It makes learning about these circuits that much more fun. Also, after a bit of time, I can begin to understand how we progress from an initial thought to an "actual" circuit from the mind of a master.

I never even saw them listed.... I was on the site this morning, and then went to the store right after the article was published. I'm not seeing any reference to them at all in the store. Were they already pulled...? Was I looking in the wrong area?
