I've looked a bit for a nice R-390A to go with my National HRO 60 and
Hammarlund SP-600. A local audio shop clearing an old warehouse has offered
me a combo of a Stewart Warner-built R-390A (Serial Number 27) and TMC
(Technical Material Corporation) CV-657A (BuShips) SSB adapter they are
clearing from an old warehouse. Both units light up, but I hear only noise
on the headphones -- I can't tune in even local BC stations. Both units
appear to be complete --covers in place, correct knobs -- and in fair to
good cosmetic condition. They also have a EAC R-390A in much worse condition
they might throw in.

These used to be common as dirt on the surplus market. They aren't any
longer. They also aren't much fun to work on.

Contact Chuck Rippel in Chesapeake, VA. He is doing a grand business in
refurbishing R-390s, and he'll probably be willing to make a trade for
several old units and get you a rebuilt one.

I would appreciate any thoughts on their value, and a possible source of
information about the TMC SSB unit. I remember seeing a bit of TMC gear back
in the 50's, but haven't seen any advertisements for them dating after the
60's.

The TMC SSB unit is unavailable and everybody wants one. The last time I saw
them for the sale they were in the $500 range.
