Title: Best JFET testing/matching PCB?
Post by: culturejam on December 19, 2016, 05:32:07 PM
I really need to do some JFET matching, and my old perfboard tester circuit has long been lost to the trash heap that is/was my work space.

I know there are a few projects out there, but does anyone have a strong preference for one over the others?

Rully's is pretty good. Here's an OSH link:

I use the one from the original Nom Nom release. The Rully one is pretty good though. If you order them from OSH Park let me know. I'd like to have a spare, just in case. I'll of course PayPal you the $$ for it.

Cool PM me and I'll pay pal the $$ over tonight.

FYI, I'll be releasing a small bundle of utility PCBs most likely in January which will include a JFET matcher. Also, germanium transistor tester, 14mm pot mount, 9mm pot mount and a multi-voltage board for prototyping. These are all actually done, just not released yet. Sorry for the hijack.

And I'll have to order those as well. I was gonna etch a Germ tester but you just saved me the hassle. Put me on the list!!!

I'll just wait, then. It's not a JFET emergency.  ;D
