Ok....så maybe when VFETs are sold out the kit may be sold without VFETs and be sourced other place?
Are the VFETs matched?

Other Fet is IRF250. Kit will also be available without Vfet. Vfets are matched, but
this is not required. Initial offering is with 2SJ28. Second offering is similar but not
identical with 2SK82.
2SJ18 and 2SK60 will work, but less power.
The kits can be used with P channel and N channel Mosfets instead with small
modification.

Can't wait, then I'll be behind by 4 amp projects 😉 I have a small collection of both J28 and K82, though I have more J than K.
I'm still finishing my Aleph-J, but would love to join the greedyboyz club. Is acquisitivness the sole qualification?
well, besides greedy, you must show some extent of pushiness, and no small amount of non-patience .... and rudeness
if you take a look around, majority is exactly like that.

Nope. You have to make a donation to the Church of the Holy VFET.I'm still finishing my Aleph-J, but would love to join the greedyboyz club. Is acquisitivness the sole qualification?

Nice! Is the IRF250 used for both amps?
Whenever we talk about this mythical machine it always
‘your a greedy boy’
‘patients’
‘how can you be impatient about a free design’
‘heatsink are in the mail’
‘Your loves in the sink...’

I’m in the middle of an Aleph J build myself, but I will look out for the next VFET amp kit to build after I finish the Aleph J. Having built the first Sony VFET kit and thoroughly enjoying it now, I am certain my Klipsch Forte II’s will match up very nicely with this single-ended VFET design. Thank you Mr. Pass for your generosity.
