FET Reassurance for COVERT Build

[Chuck D. Bones]

I'm sorry to hijack the thread, but what would be a good through-hole alternative to the MPF4393s? 2N5457s?

What's important is to get a JFET with Vp between -1V and -2V. Some 2N5457s will work, some will not. If you want to sub JFETs, you need to be able to test them.

Thanks, Chuck. I do have a DCA55, so I'll test a bunch and see what I can find.
