[Premium-Rx] Sylvania AN/FRR-81

[Les Locklear]

I owned several years ago a Sylvania built CU-1280/FRD-10A(V) Antenna 
Multicoupler that was built at  the same location.

Judging from the number of tubes it had to run hotter than that Multicoupler 
which ran hot as hell.

Nice room heater, as it certainly wasn't accepted as a receiver.

Either someone had certainly seen (at least) an R-390 and/or R-390A, or
evolution converges a lot faster than I had expected.
