I may be wrong , but non matched device will let some dc through , and we dont want that for the input trafos
.

There are loads of listings for matched pairs at a much lower price. I'd ask the other listings if they would do a matched quad for the price of two pairs.
The Punkydawgs Jfets are known genuine.
This is also true of Alwiet.
The rest? Unknown. There have been a whole lot of fakes lately.

I don't believe the problem is the price of the FETs, but the postage of 35E and additional import taxes depending on where you live.
how much would you ask for these jfets , if you were the seller 😀
let me guess 🙄
.
Erm... 7.25$ shipping charge inna US . Still no bargain but hardly prohibitive either
Considering what most people will have paid for a case and big transformer.
The cost of such a vital component to a Pass design as the J-fets is tiny.
Buy genuine and enjoy the finished product.

I was listenig to some 70 rock and folk LPs last night with a good vine in the glass and the house still as the grave. It hit me how the F6 conveied music in an utterly un-pretentious, believable and involving manner ( I was only on my 2nd. Glass of vine 🙂 ).
The rest of the chain is not high-end in any way, diy Aikido linestage, Boozehound phono, Sowter SUT, cheap DIY wires an interconnects, my old and battered Altec A5s, the Denon dl103 has its limits and my DIY Lenco has some motor noise. Still the sound was sublime and at relatively low volume. Look forward to hear the M2 once I finish it.
But once more I have to say Mr. Pass the F6 is a great amp and I look forward to build and test more your FW amps.

The F6 is an amazing amplifier, but much like the F5 very revealing and unforgiving if the medium and other components are not it's equal. With horns that are sensitive and revealing this is more evident. When everything is right, system, source, both sound fantastic. If not the faults in system, source will be more evident. With my horns I prefer an amplifier that is a little more forgiving. Just my observation after building many of the FW clones.
My Altecs are quite revealing but not as revealing as the Lowther horns I had for over a decade, although I think the F6 would be ok on Lowthers if the rest of the chain is in order.
ZM M2 will be singing soon 😉
