I've found all the parts for this project except for the ZTX330 and 2N5950
transistors which seem to be extinct. The 2N5950 is available at some
commercial venues but I only need one of em. Are there readily available
subs for these? I'm getting a little discouraged. Thanks.

I'd think the 40673 mosfets harder to find though easy to substitute.

The ZTX330 is generic and a 2n3904, 2n2222 or similar should
work fine. For the 2n5950 I'd use a MPF102, 2n3819 or J310 fet as
those are easy to get. The transistors used are in non critical
circuits so substitutions should easily work.

Generally speaking the transistors and IC used reflects those
available to the author and reasonable substitutions will work
with no degradation.

The only parts that require care are the MAV-11 MIMICs and the SBL-3
as they helps define many of the modified recievers desired
characteristics.

These folks have a decent supply of 40673s. They advertise being
"Leaders on the trailing edge of technology". I don't know what their
onesy - twosey policy is, having never done business with them.

Also, search for "NTE" equivalents.
