A lot of early 5 tube TRF battery radios aren't in Rider. Most of these radios are very similar using 201A (01A) tubes. I suggest using Stewart Warner 300 series schematics.

This radio was made in 1925 and originally cost $66. A lot of companies made radios for only a couple years. This was probably one of them.

After a while, I try to avoid any more 3-dialers.

I sure have to agree with you. Found out too late after I had a bunch of 3 dialers. The Stewart Warner 300 series schematics can be used for most of them. Biggest difference and most interesting are some unusual methods to drive the tuners.

:There were many manufacturers of 3-dial, 5-tube TRFs, hundreds if not more. Quite a few were garage-based or other such operations. They are all interesting, but most are very similar, at least electrically.
