Classic symptom was , car would start and run as long as the key was in the start position , but when let to return to the Run position after starting , the engine would instantly quit (as the boost 12 volts went away and the ballast wasn't there to provide the running voltage)

Yes I remember the Chrysler ones, and in most cases when they went bad, they were cracked, and easily spotted. I didn't know about the radio wire, what was the purpose of that wire in radios...? Most had a big power transformer so I can't imagine a reason for a ballast resistor....
