Hello, I have a 1969 Porsche that has an original, Blaupunkt, radio.
The AM works, but the FM does not. I was trying to find information on
a "FM to AM converter". If anyone has a schematic, or any advice at
all, I would GREATLY appreciate it. Thanks in advance!



I'd call these guys up (http://www.radiomanrepair.com/) and see if
they'll provide a quote for repair of the OEM radio. You'll have a
neat, operating vintage car radio, and you might even get the cash back
when you sell the car.

It isn't trivial to convert FM broadcast signals for reception in the AM
band. You pretty much need a back-to-back FM receiver and an AM
transmitter to do that, and the RF work associated with homebrewing a
converter would (honestly) place the task out of reach for anyone who
needs to ask how to do it. :-)
