Hey John
I just realized that the unit shown is not your unit. It could very well be that your unit, is a Six Volt Unit, which will of course require a Six Volt Power Supply??? If that is so you would need the guts of a Six Volt Battery Radio. I think that the Car Radio should be from 1954 or earlier model of North American Cars. Also the matching of the Power Transformer in the donor radio should match 250 Voltage as well as the ma otput.
