[Premium-Rx] Superior Preselector AN/SRA-38 ...-50 Is anyone interested?

[AKnott at WTD71.de]

I use a group of manual tuned preselectors which are the very best I ever
used. They are named "Antenna Coupler Groups AN/SRA-38, -39, -40, -49, -50"
and each unit consists of four magnetic coupled LC-circuits which are tuned
by a variable air spaced capacitor. They contain no ferrite slugs to produce
intermodulation or any semiconductors! These preselectors came from old
combat ships from the US-Navy. Possibly they are relatively easy to find in
the states. I even own a technical manual and maybe I find the time to write
an article about them and add some pictures and diagrams... Is anyone
interested?
