Deforest RJ4 Spherical Audion Tube Radio Repro WORKS
Deforest RJ4 Spherical Audion Tube Radio. I put together this reproduction of the early version of the Deforest RJ4; this is the 1913 version of the Deforest RJ4. I attached it to a loose coupler (which is pictured but NOT included), headphones, an antenna and ground, and WBAP came in loud and clear. Worked great. The loose coupler is not included in this sale but most likely I can supply you with one if you do not have a tuner. The reproduction spherical audion IS included and works.
What is great is that you are listening to radio like the very days of radio when it was primarily used for emergency communication.
