If we can find a source for the 2SJ109 & 2SK389 s I think I am just going to order the boards and then offer the remainders on a fist come first serve basis.

Are these the boards from the Headwize thread?

Are eight output devices needed per board?

Looking at Kevins original post it looks like 4 are the baseline? Am I missing something (probably)?

Yeah, the plan is to use the current gerber files that are posted in the Headwize thread.

Seems Mister Gilmore has the same concern about those "zip jfets" eh?

Nope you are not missing anything.

Great! I got a ton of 2SJ109 & 2SK389 that I've stockpiled. I was going to throw them away, but now I've got a project for them.

[KenW]

me too !!

Come on Kevin, give us a Dynahi beater

If it's better than the Dynahi and beta22, a certain builder might want to start warming up his soldering iron. This boy has more room to play with now.

4 for me.

[asebastian0]

Make that 8.

Four for me as well, though I only have sk389 / 109 for two... or three. Gotta check parts again...
