Stewart Warner (previously "unknown") 1 tube regenerative radio
#1

Some of you were interested in seeing this one tuber from the local museum. A few pictures first:

It uses a single #32 tube. It has 4 wires coming out the back and I can just see traces of color on some so I labeled them in the schematic. Here is the schematic if I've traced everything correctly:

The movable tickler coil has continuity however the fixed coil is open. I also hear a slight scraping in the tuning capacitor as it goes through its rotation. I've labeled the chassis as ground. The rotor on the tuning cap is grounded. I'm in the process of searching through the many one tube schematics on line in hopes of finding a similar one. So far a few similar but none with a 32.

The case is cardboard with the pressed foil designs on the front, very neat I think. It will take some careful cleanup but should look a little better when clean.
