Tough little buggers...and at 15V and about 10 - 12mA (Mr. Pass?) they'll be singing for a long, long time. I think he is also planning on lowering down to +/-12V using batteries.
There are several things to discourage competition from cloning this amp:
1) It must be soldered by hand, and it takes a lot of time (impatient competition will roll their eyes upon seeing it-wont even think about soldering 3000+legs)
2) Papa will purchase all remaining stock of J-fets, so there won't be any left for competitors
The good thing is that, when Papa gets bored of these amps, he will have years supply of J'fets (and some even for us). Imagine a conversation after 10 years: Halo, Nelson, I want to build a Jfet preamp, but I can't find any jfets...
Papa: Wait, I have some on the boards of those beasts, somewhere in my basement...lemme unsolder some and I'll send them to you...

did I told ya that I saw pic ( on secret AR2's server ) of entire shelf , linen with these boards as books ?
by my calculation - there is around 72 of them ....... so you can count number of jfets ......

Cool thread, sorry it took so long to find it. I'd be interested in seeing some measurements from the final products. Were they ever taken?
Assuming 1000 Jfets per channel, by loosing one, we loose 0.1% of sound quality? Somebody may hear that! 😀😎
Hi Nelson,
so you finally had time to finish your a thousand jfet beast ;-)
Amazing how you regularly come up with something completely different (TM). Really nice fun stuff.
I hope you enjoy your work at least as much as we do. Thanks for sharing.

Nelson,
Jan Didden told me that he heard the working amp at the BA festival.
I wonder what your own final verdict is ?

It works very well. I haven't had the time to play with it as much
as I would like. I finally got Jill to bring her macro lens back from the
coast so I could take the pictures I need, and the article will be finished
in about 3 weeks.
Jan has chosen my SIT article over this, so then I have to decide where to
put it. Maybe AudioXpress.
