- Model 84B was the third of a series (models 80B, 81B, and 84B) of low cost 4-tube cathedrals that used a regenerative combined IF/detector stage to maximize sensitivity with very few components.
The early version (1934) had a round speaker opening with three vertical bars. The middle version (1935) had a lyre-shaped opening with three vertical bars. The late version (1936) had a continuous arch-shape extending upward from the base, and an oval speaker opening with five mostly vertical bars.
Model 84B continued onward for one more year as model 37-84B, with two more cabinet styles, and a new tube lineup (but still using a similar circuit).
