ZM,

Your spelling is as bad as Red Volvo's! What are you doing wrestling with gerbil humorists? Is there money in it?

Acronman is a very reliable supplier IMHO.

I'm in the middle of matching 230 pair of K82 and J28, but of the
KE33 rank. I'm testing for Vgs at 20V Vds and 0.5 and 1 amp,
transconductance and Drain resistance.

It's very tedious.

Yes, Acronman is good, and the package used just a week from Singapore to Norway.

I have a handful of K82 and J28 (both KE33 rank), I am planning a push-pull amplifier, but after some PM'ing with Michael Rothacher I decided to start with a single ended amplifier to gain some experience with the VFETs. Maybe that will help me to avoid frying the complementary pairs.

My ultimate goal is to end up with something for my Quad ESL-63s.

Sounds somewhat familiar.

Default Robert, Arlo, Nelson and me

Some years ago artist Arlo Guthrie performed at the Tønder Festival in Denmark (Tønder Festival 2013), and I happened to be there. The very entertaining Arlo Guthrie compared his song writing to fishing. No matter how big fishes he caught, Bob Dylan would be further up the river getting the really big ones.
So is it with me (and others as well) and Nelson. I remember I once thought something like the ancient W. Marshall Leach, Jr. common-base moving-coil preamplifier topology could become a nice I/V converter for a DAC. But Nelson Pass made the D-1 DAC many moons ago, and now he also has the Zen I/V converter.
Anyway, good to have you here Papa!
