Atwater Kent Model 184 (1935, 1936)
The model 184 is a 4-tube regenerative super-het from the
penultimate year of Atwater Kent as a radio manufacturer. It
was introduced in the summer of 1935 as part of the
company's line-up for the 1936 model year, replacing the
previous season's
model 854. The list price was $27.50.

The 184 tunes the standard broadcast band from 540-
1712kc and has tube line-up:-  6C6 (oscillator/1st detector),
6C6 (2nd detector), 42 (AF power) and 80 (rectifier). Like
many of the low-budget receivers from this era it does not
employ AVC and has the volume control situated at the
antenna input. It was upgraded from the earlier model
to use the more modern 6V tubes rather than 2.5V types.
The circuits are otherwise practically identical.

This model uses regenerative feedback around the 2nd
detector in lieu of a dedicated IF amplifier. The manual
states that once the set has been connected to an antenna
and ground, the sensitivity screw at the rear of the chassis
should be adjusted until the set falls just short of squealing.

The center knob is not original. In the photo below notice
the large 8" loudspeaker contained within this set, which
ensures good quality of tone!
