1925 Crosley Super Trirdyn Special

This set contained three tubes, probably type 01A, but other types would also have worked equally well. The circuit was an Armstrong regenerative circuit with two stages of audio frequency amplification. It was battery powered, as most sets were in 1925, and the cabinet was made out of solid mahogany.

These Crosley Musicone speakers were the type normally sold with the Super Trirdyn Special. The full ad for these speakers is contained in the "Tube Box Art, Labels, and Advertising" section of this site.
