[Milsurplus] Unknown Modules

[elden meyer]

 Good Evening Michael and group,

These are, as you supposed, IF strips from airborne radar. The ones I have had were from the SN-7 synchronizer of the APQ-13 radar set, although I believe other sets also used similar modules. Later modifications of the SN-7 added a small chassis with a 6AK5 preamp ahead of the strip.
Back in the day I sort of recall someone using this in a homebrew TV receiver.
