Uh yessir Bob, sure sounds like you need a CPU. That's one of the best ways to damage a 5-Volt CPU chip, feed excess voltage into it.
The only source will probably be the folks who had it made and marketed it, "President Europe". They were located in Paris, France once upon a time. Never have tried to get a part from them.
Seems to me an outfit named "Palco Electronics" was advertising that radio on their website 3 or 4 years ago. I just assumed that they were the folks importing the radio from President Europe. If anybody on this side of the Atlantic Ocean would know, I think it's them. If they're still in business. Tried to buy a service manual from them for that one years back. Never got a reply to any e-mail I sent them. Turns out very few of that one were sold around here, and I lost interest in pestering them.
