Walgreen's Aetna model 604, 606 or 653 from 1936*
(*anyone with the correct ID, please contact Me)

A most attractive cabinet design with a beautiful
multi-colored dial as sold by a Drug Store chain!

I acquired this from the estate of a now deceased friend on mine (Jerry Talbot) and recently restored it. I did not like at all the poorly done, Tung Oil refinish job done that was done by someone in the past. It looked so amateurish that it sat on my project shelf for a year or so. I always thought it was too nice a radio not to be restored properly.

The cabinet was done by my friend Gary Marvin while I tackled the electronic restoration. This turned out to be real challenge as well because it also had suffered a previous poor attempt at repairs by someone. What should have been a straight forward restoration was anything but that. Someone had changed and modified much of the circuitry and getting it back to it's original condition was complicated by errors in the schematic provided by my Riders library.

After re-wiring it according to my interpretation of the schematic (with errors), it worked poorly. Too much audio distortion and poor AVC action. I modified the bias and power supply filter circuits and added AVC to the first stage (RF & 1st IF). It now works as good as it looks, very selective and sensitive throughout the dial.
