1925 GREBE MU-1 Synchrophase RADIO Art Deco Mahogany CASE wood grain



1925 GREBE SYNCHROPHASE MU-1 Radio Reciever with Mahogany case. Untested, interior and tubes look clean. Scratches on the case, please zoom in on all pics.

The radio includes a good set of tubes. If you’d like to operate it, you’ll need a good regulated power supply (I’d recommend an ARBE III), a cone or horn loudspeaker from the 1920’s, a strong indoor ground connection and a longwire outdoor antenna (ham radio type — about 120 feet long and 20 feet off of the ground). It will also help to have had some experience tuning a 1920’s battery radio. Unlike later AC radios, you don’t simply plug them into the wall and turn the dial to tune a station.
