[sdiy] LM336Z-5 and 2N3904 Equivalents

[vitreousflux]

Thanks, guys.

Mouser seems to have only 1 2N3904 transistor in the TO-92 package - all the
rest are surface mount from what I see.

Anyway I think I'll go with the 2N4401.

I plan to (attempt to - HAH!!) match transistors for the SBM ladder filter.
