I am working my way through Wes Hayward's book EMRFD along with Doug DeMaw's
book W1FB's QRP Notebook and am creating a new part order. Yes, I will
receive discrete parts for my Christmas present. Since I needed something to
put under the tree a nice box from Mouser would look just fine.
Usually a quick Google search will return several choices. Search for
2N substitution. I tried it and got several choices. You can
usually search for the exact device and get the entire specification
to compair.

I need some 2N4416s and some BB104s and find them
either as scarce as hen's teeth or dear enough to make
Croesus cringe.
Kevin brings up good points. (Probably any general purpose FET will work,
Kevin.) For a real challenge, try finding a dual-gate MOSFET such as the 40673

And yet, the lowly 1N34 germanium diode is still going strong. Why is this
