Default Dual jfet

If you match both Idss and Vp, they'll have the same Gm at all currents
-- in theory.

Depends on the particular application, but this sounds reasonable. However,
rather than IDss, I'd shoot for what ever bias current they are operated at,

I'm building a circuit that calls for a dual monolithic
jfet. Can I use two discrete jfets that I have matched
for IDSS in the circuit? They are in TO92 plastic
cases, I can glue the two in contact with each other
so they end up at the same temperature.
