You can trace the wires in the underside photo for the "schematic".
Hey, it's fun, it works, and sounds OK to me. 😉

Hey Drjbf1

Me too i have few of KD-33 grade 2SK82's and i am in to quick build
with point to point technique , but could you share more informations
about caps values ,components potentiometer and PSU ?
Its simple circuit but i work much with schematic or little better zoom detailed photo's please.
Maybe new thread dedicatet to your work ?
Thanks its very interesting diyer friendly and fun project for Sony Vfet's.

Have a nice day

My work certainly does NOT deserve any dedication! 🙂 I just cobbled this together without any optimization or allowance for headphones different from mine which max out at 30 mW. I thought setting the gate bias differently was not worth the effort and extra parts given the small improvement in performance. PSU is SMPS brick.

Cheers

What the world obviously is in need of, besides Peace, Love and Understanding, is a Kickstarter campain to develop n- and p-channel power SITs. ��

This is my next project. I have ordered Vfets and am trying to get all the parts together. Are there any more boards available or is there someone who wants to sell a pair?
