Hello,
I would like to experiment with a Power JFET build using the Zen 9.
https://www.passdiy.com/project/amplifiers/zen-variations-9
I'm looking to build it using Lovoltech LU1014D but want to use a current production part.
Can anyone suggest current SiC production parts?
Poking round I found these:
Which Power JFET is preferred N-ON o N-OFF?

dunno about these ( will check later ), but I'm going to check UJ3N065080K3S
2 things - it must have DC declared on SOA graph, and you must know how to deal with highish Ugs

The shape of the characteristic curves are different. In the Zen v9 & F3 the LU1014D is operated at the point where the transfer characteristic shows concavity, is triode like, at a Vds of ~2.5V. I don't see any such operating point for the UJ3N065080K3S, it's pentode-like.

well, that's the fact
LU in F3 ........ one must observe entire arrangement
it is having triodish transfer characteristic helped with significant degeneration , and cascoded to keep low Uds
that graph above - it is for solo LU(LD) - for my venerable eyes, far from triodish
when not degenerated, LU is crazy part, having multiple xconductance of IRFP parts, shown and verified in LuDEF - minuscule THD of amp without NFB, exactly because of that fact
