Bob, good thought. I have exploeder that avenue, but it not the easy. most AM/FM radios are 12 volt neg ground. what make this circute unique is that is 6 volt with a built in 88 watt amp.
I have even thought of using a househiold portable radio that runs on 6 volts, but I cant find anything that is sutible. what key is to be able to use the tube radio's orginal tuning block to oprate the soldstate tunner.
For those who had these radios converted: If its not too much trouble please let me know if there is any stamping on the electronic board that would give away the manufature and or company that makes them
Thanks,
Alex
