Halfway through my VGS testing my hope is fading on some good matches!

I may have got it backwards here. I was trying to match P's to N's when I should be matching P's to P's and N's to N's?

Sorry about that. I am working on a board respin for my FE. If anyone wants the old boards, you can have them. The new boards will be available at roughly double the cost (to account for the previous screw-ups). The output stage is still being tested - need to get on a drill press at some point. The FE would also make a pretty nice preamp, I would assume.
If I may, I'll take 4. I reckon I might use them for a few things - a pre amp seems logical!
Um, and happy to pay something too. Let me know what's good for you
And here it is with the bracket.
I would like to know the thickness of this bracket. I found some on ebay but they are 1/4" thick. From Papa's picture. I extrapolated to be about 3/8" or 3/4" but my eyes are getting old. Is 1/4" OK or I need something thicker? This is for a similar Vfet (1 or 2) project.
TIA
Demo
Anyone in the Twin City's interested in hearing the V-FET part 2. I will be demoing my set at the Audio Society of Minnesota meeting tonight.
I'm hooking them up to our Big Magnepan 3.6's. I'm planning on rolling them off at about 80hz and using the subs so I can get a little more out of them.
Fun for all...

The part 2 amp is more dynamic and has a bit more detail. The part 1 amp is very nice, a bit looser on the bottom and it sounds great on horns.
I like them both, it's just a different type of wine.
What I want to know is can I get a Mosfet amp with Schade feedback to sound as good as these V-FETs?
Sometime this fall I will find out.

Very Cool,
I have a pair of modded Maggies and eagerly await your findings.
Which subs will you be using?
Are your VFET amps using single complementary pairs per channel or are they paralleled multiples?
Since the Maggies love current, I'm curious what minimum quantity of complementary paralleled pairs of the 2SK82/2SJ28 VFETs would be needed to properly drive them full range.
Thanks Botte.
