Default Op amp + Vfet 's 60|18 = Seychelle

Share this schematics if you have 2SK60 and 2SJ18 in your drawer.
Simple build use only half of the op amp and pair of Sony vfet's.

Soundhappy, I'm currently driving SE common drain SIT with opamp. It sounds good, but not enough voltage swing, I like the LED thing, I'll try it.

Thank you for the input.

Good luck finding the parts whose Vgs matches the six Leds.

Personally I think I would use a TL431 and have it adjustable.
