Nikko Beta 1 and High voltage JFET
Hello everyone, I am working on repairing a Nikko Beta 1 preamp. This preamp is pretty unusual with +- 66V power rails. I need to replace a JFET 2SK95 (Shindengen) with VDS max 150V! All my searches suggest there isn't a modern equivalent. I did manage to locate its P-CH partner 2SJ32, but I...- Junhyong

2SK97 dual N-channel JFET spec measurement & substitute
Well the funny thing about me writing this thread is that I don't even own an amp that uses the 2SK97. I got interested in the topic because I was doing some measurements of the 2SK129A (another dual N-JFET) which appears in my Sansui AU-X11. Anyway, it looks like the 2SK97 is used in some... -
Replacement JFET... what's difference between transistor?
I'm working on an old organ at the moment and I think I'm gonna need a replacement for a JFET... it's a 2N4360 - the only equivalent I could find was an NTE326. I was hoping someone could point me in the direction of a better one. Also, I notice tha tthe terminals a DGS and not CBE etc and I...
