Can anyone help identify an old coin op radio. It's a cabinet style about 3 feet tall and about 19 inches wide. It plays 30 minutes for a nickle. Looking to rebuild it myself. I can reskin the cabinet, but am in need of a schematic if available

The address is in the old part of Dallas. So the building might still be there, and maybe someone remembers or has information. Otherwise, it was a tiny company that didn't produce a lot of radios.

Can you post a pic of the entire radio, showing the coin slot as well as the dial?

Here is a generic schematic you can use to identify the major components. Cap and resistor values may be different in yours, but will be similar. Basically if you replace caps that can be identified by their markings, do that, one at a time. The high voltage electrolytic caps are the most critical.

This schematic shows the 30 and 20 mfd polarized electrlytic capacitors. The negative leads are combined and go up to the B- bus which runs horizontally thru the middle of the drawing. Your radio may have different values for these caps, but 30 is best for the first one from the rectifier tube. I had to alter the cap symbols because the artist had them reversed.

Thank you very much for the schematic. I will start to run through it when I get home today. Heres a pic of the front.

Forgot to mention: the coin apparatus is loose in the pic, but was installed and functioning when I got it.
