[Yaesu] N-Channel MOSFET Replacement

[Jim Hargrave]

Don't forget the 3N211..its in the same family. I have used it in many
applications. It used to be regular stock at Radio Shack but I can't find
the number.

The 3N159, 3N201, 3N202, 3N206, 3N209 & 3N211 all cross to an NTE454
They have a little better gain and lower noise factor than the 40673
(NTE222)

All are pin compatible.
