It would be awesome to see added the 2N5484, J201 TIS-58 N channel-Jfets since a lot of circuits use some of those Jfets since there are not good substitutes for those Jfets. Here are some datasheets ...

The x1 voltage amplifier or “buffer” is a standard building block of analog design. This article presents the design of a discrete, low-parts-count, high-performance, matched-transistor buffer, and ...

There are a bunch of 2N5484 JFETs for analogue signal switching, lots of 1N4148s and a few Zener diodes”, he writes (PDF). That document also provides the circuit diagrams – around 20 of them, all ...
