Repairing an R-390A, the Best Comm Receiver of the Tube Era Part 4, on the air

Purchased at Dayton Hamvention for a rainy-day price of $150 and severely damaged in shipping, this crusty R-390A of Motorola manufacture is repaired back to original specifications.

SSB stations are tuned-in using the R-390A in this demo.
