Default High Power Zenquito PCB group buy?

I have designed a board for the circuit below. I particularly like it for it's simpliciety and potencial power. I'm at my work computer at the minute so can't upload the board design until tonight but it's double sided and uses one pair of double die FETs of your choice (ECW20N20-Z and complementry for me) to give around 300Wrms into 4R. Distortion figures have been simulated HERE. I have had quotes for the boards which measure 56mm long by 40mm wide, they would work out to be 5+shipping to your country. Ninety boards could be availible.

Would anyone be interested in something like this?

Well, from my point of view it'a a pity that people are not interested in your proposal. Because the schematic/amplifier has potential for a good sound.
It was discussed also in the past and with a couple of tweaks some members reported at the time an increase in sound quality.
Maybe it's not the topology/schematic in itself the reason for topic 'silence', maybe dual-jfets used in input stage (pretty unobtainable and pricey) could be the reason.

I find that not only does it have potencial, it does in fact sound very good, I have similar one but using BJT as cascodes. The problem is obtaining Jfets.

Maybe our members which tweaked Zenquito in the past will want to share the tweaks they did - which I suppose that are related mostly on the power supply side.

I can't believe there's no newer replacement for the 2sk170/2sj74. Is there anything even surface mount?
