Notes Chicago Radio Labs clone of the Adams Morgan Paragon RA-6 with binding posts moved to the top of the set so they would better match up with the CRL AGN line of detector/amplifiers. The variocoupler (center dial) rotates only 90°.
In February 1921 Chicago Radio Labs announced the first use of the "Z-Nith" trade name on the Z-Nith Regenerator which was previously known as the Paragon Short Wave Regenerative Receiver. Adams Morgan had forced the new name change in early 1921 after forcing CRL to give up the use of the trade name Paragon.

The picture of the Z-Nith Regenerator Regenerative Tuner shown above also includes the rare CRL AGN-2 Detector, two-stage audio amplifier that sits above the tuner. The binding posts were moved to the top of the tuner to assist the connections between the two units.
