A rare "Treasure Chest" model of the early Seattle, WA
Packard-Bell Co.  A four tube Super Heterodyne.

I Have had this radio for more than 30 years. I thought it was nothing more than the common, simple 4 tube, poor performing TRF found in many small 4 tube early 30s radios. I recently decided to do an electronic restoration on the set and put it up for sale.

To my surprise, I found the circuitry is not a TRF, rather; a Super-Het! Yes a 2 tube Super-Het plus rectifier and 1 stage audio. I could not find a schematic for this Packard-Bell model but after an extensive search a came up with a similar schematic for a "Packard" model. I edited, modified and improved the schematic to fit the subject radio's circuit. I then performed a meticulous electronic restoration.

All done, now a test drive. Thinking this will be one the worst performing radios ever, sure enough, no sound, just slight static across the broadcast band and a hum when touching the # '57 grid caps. Next provide an IF signal; nothing!  Gave it maximum 255 Kc signal level from my vintage GE model SG-3 RF signal generator (about 1.5 volts) and I hear a faint 400 cycle tone. Who ever attempted to service the radio at some early time had the IF padders way off. After an IF alignment and connecting my "long wire" antenna, the radio came to life. After a tweaking of the tuning capacitor padders, to my surprise, loud clear sound across the dial with no squeal or howl! This radio (with about as simple as circuit as a super-het can be), performs exceptionally well.

Now offered for sale: The finish is original with the usual wear with minor scuffs and scratches. The case is solid, no damage, water stains and has original grill cloth and  knobs. The case and chassis are clean, no evidence of insects or rodents have resided therein.

The work done includes:

TUBE LINE-UP:  57 (RF, Osc., Converter & 1st ), 57 IF, 47 Audio & 80 Rectifier.

 < Improved schematic for above available
