RCA Radiola IIIA
Four Tube Radio



Built in or around 1924 by RCA.
It uses four WD-11 Tubes. This radio is the same as the right side of the  RCA Radiola III radio above.
In fact it is the same. A balanced amp is added (left side) so it could drive a horn speaker.
This radio is new and was never used and was found in storage
with other items from a old radio repair shop in Concord, California.
I also have the original box it came in.
Tuning Range: 400 kHz - 1540 kHz (750m - 195m) via an array of antenna terminals.

Home made loose coupler probably built sometime in the 1920's.
It was found in a barn in Ohio by the person I bought it from in 1999.
It had a Pacent model 30 detector with it also. You can see the detector at

Atwater Kent

Another project waiting in the wings.

Hombrew Crystal Radio


Another homemade crystal set probably made in the 1920's also.
I know nothing of it other than it is a mess!
I intend to restore it to working condition.
