Another thread I found on this subject didn't really go anywhere, so I'm posting my own if that's ok.
Getting all my parts together to build the Minnow (FSH-1) and realized the presoldered-to-adapter MMBFJ201s I was expecting are backordered.
In the schematic snippets below, the J201s are Q1, Q4, and Q5. Q4 seems to serve a different function than the other two, which I think are just buffers. I have 2n5457/8s on hand, would those be suitable replacements? If it's absolutely vital that Q4 be a J201, I'm okay with biting the bullet and shelling out the $5 to get one from amplified parts. Any other JFETS people have had good experiences with in this circuit?
P.S. Thanks for all the help on my other forum posts, really learning a lot!
