Anyone know anything about these JFETs or recall ever seeing some in any specific gear? Not sure who made them, but the packaging is TO-126. There is next to no zero info online about them that I could find. I've got 4 complementary pairs in each stage (line, MM, MC) of my Stax preamp (Echowars mentioned this JFET in the Stax's repair thread). The preamp also uses K117's, but those can still be found. As difficult as it might end up being, I'd like to track down some spares, or a good drop-in replacement. Just in case something ever goes wrong again, as it had an issue with a K117 in its last life. Worst case, I could move some around between the different stages, but then something would still not be working.
Any help would be much appreciated!

just saw this message a year late ...
i have only ever seen these devices in an old Nikko Beta III preamp in voltage gain and output stages.
never seen data sheets for them either.

yes, sometime last fall i also realized they were in the Beta III. someday i will grab one, and not just for parts -- it looks like a pretty nice preamp.
