Stewart Warner (previously "unknown") 1 tube regenerative radio
#20

Time to write the final chapter on this restoration. I went back and checked all the connections. Sure enough, one of those grommet style connections on the coil was not making proper contact with the connection lead the grommet was holding so I added in some copper braid to ensure it was solid. It was the #1 connection seen on the coil in an earlier post. The pic shows the braid which went through the grommet and was trimmed off on the other side.

When I tested reception with my SSTran I was able to tune in on the broadcast band nicely. I could not pick up our one local AM station but I only have about 30 feet of antenna. Here's the radio back together. It will now head back to the Bandon Museum.
