We graded them a little more finely so as to be sure of getting relatively equal
distributions, but actual matching was not necessary, so the cost is the same.

BTW, Patrick's estimate of the cost of the P fets was one channel only.

At $5 apiece, we have almost $12,000 worth of Jfets. I believe I pointed out
elsewhere that I left the leads on the parts long, just in case I needed them

So when someday you need them, just taking them out; it will still work, just slightly worse, that is until enough have been taken out.. (I wonder why I am thinking about HAL....)

All right Mr. Pass...I'll make sure you get them back when you need 'em.

> Besides, Patrick, I have a photo of you holding one of the boards. You had
your chance to run away with it....

I already sorted out my own solution.
No less freaky, I can assure you.
But somewhat less costly .....

So are the boards going to be available at PassDIY, or in the DIYAudio Store?

Hm...smells like El-cheapo version of the Beast...with some cheap J-fets, a group buy would mean a quantity of 10000-50000 or more pieces. If one could get 2000 jfets for 200 bucks, then it becomes a viable option....

Isn't it a great chance for producer ? We've got niche market here. It's probably better than The Long Tail theoryin economics. Maybe someone should let them know.
