Need Info On Hastings FM12 FM Tuner
 

I have a pristine Hastings FM tuner model CT12, that was designed in the 1950's for adding FM to automobiles. These are rare, with seven tubes, and beautifully designed. I am seeking any servicing information, including a schematic. Please help. Broadcaster, email brdcster@gmail.com

Maybe a picture would help, as many of us never heard of the make.
The only one, I heard of at the time was Gonset. It used the B+ from the AM radio. :scratch2:

I'll post a picture this weekend. This unit gets it's B+ and filament voltage from the car radio, and has provisions for a separate FM antenna
