I have decided to build up some IF strips. I've never done this. I would like to see a discussion r.e. choice of transistor (what, aside from Ft determines a good candidate?), and I would like some recommendations of various types (i.e., some BJTs, some mosfets, or other types) so I can look up their specs, and maybe buy some.
Oh, and if there are other comments r.e. IF Amps, I'm interested. Also feel free to PM me at
Thanks, Bob, WB5EMX

From what I've heard, you ideally want vintage junk box transistors, as their are a lot of counterfeits on today's market. Alternately, you may want to buy in quantity from a reputable electronics distributor.

Sometimes distributors will have great deals on parts they are closing out because they are no longer suitable for use in new designs.
Free parts--just send an SASE with $5 postage!
