Yet another radio mod, this one I doubt anyone would replicate. At my mom's house there is this 8/16V @ 5A power bus, using the old 1/4 inch Jones plugs. Why these voltages> It dates back from the time we had a model railroad setup, and the lights in it used 8V. I have a few 4BE6's and 4AV6's, and a 17V centertap transformer I could wire backwards to get the plate voltage. The rectifier became made of sand, and the 50C5 became a submini 5902. And the 12BA6 changed to a 6BA6, and a small heater dropping resistor. The B+ came out a little low, around 90VDC, but the radio still works well.
