A seldom seen set, RCA's last battery operated model of the 1920's. Introduced in the fall of 1929, the Radiola 21 differs from the typical '20's battery set with it's unusual tube line-up. One of the first sets to use the new "screen grid" tubes. Complimented with 2 - UX-222's, & 3 - UX-112 tubes. It's performance with the 2 (well shielded) "screen grid" TRF stages is exceptional with excellent selectivity and sensitively from one end of the dial to the other. The chassis is of unusual design also and I have included extra images of it for those that like to see the insides. The center badge, the power switch and tuning window trim pieces on the front are made of repwood.

The above was just restored and added to my collection, the finish is original, I have restored the electronics by rebuilding the capacitor blocks and repairing the "pot metal" tuning chassis frame. This is the same basic pot metal "RF" chassis that was used on the Radiola 44 & 46 which is very prone to pot metal cancer.
