The Senior version included a modulator, which was also sold separately and could be purchased to upgrade a Junior.
The "D" version ($137.50), also released in 1950, included everything in the "A," "B," and "C" versions and added crystal microphone amplifier (CMA-50, $22.00). The amp could be purchased separately to upgrade any of the other versions.
