General Electric SP51B-A- MULTIPLEX ADAPTER - tube transmitter


For Sale: Vintage 1960's adapter that was used for home stereo consoles to transmit an RF signal using the AC wiring of a home to receivers that would convert the signal into audio.

Sort of like early wireless speakers.

Powers up, all tubes are included and they glow, untested, sold as-is. No apparent damage or issues.
