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.
Hombrew Loose Coupler
Crystal
Radio
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
Model 20 Compact
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.
