Why is this tiny radio named the "Super Pee-Wee"? After recently restoring the electronics, I believe I know the answer. Most tiny radios of this size and vintage have few components and are poor performers. Not so with this little guy, it's circuitry is a full fledged All American 5 super-het.  Not counting the tuning, electrolytics and micas, I found & replaced  has no less than 10 paper capacitors (some radios of this vintage have as few as 4). The underside of this small chassis was literally stuffed full of components. After completing the restoration, I must say this radio is as sensitive and selective as any of the later 5 tube superhets that I have encountered, it is a super performer!

My restoration included re-wiring the AC filament circuit (eliminating the resistance line cord) and installing a polarized AC plug to keep the "hot chassis" at neutral or negative potential to prevent electrical shock.

There are several methods of eliminating the resistance line cord, the simplest method can only be done with some model radios including this one. I just changed the tube complement, that is replacing the complete tube line-up with the same tubes, but those with a higher filament voltage. IE: a 25L6 was replaced with a 50L6, the 6Q7 = 12Q7, 25Z6 = 35Z5 and so on. This involved only a minor wiring change in the rectifier circuit eliminating the need for any line voltage dropping resistor.  All that's needed is a basic understanding of radio/electricity and a tube manual.
