AM Radio help?
With no $ and plenty time 
figured trying to get the old AM radio functioning might be a decent project. Hooked a speaker to it and hit the power and get a rotary buzz sound out of it. Pulled the cover and replaced the light bulb, hit the power...that works. Drppoed the radio and turn it on and can hear a rotary faint noise from inside. Pull the cover and listen with a hose to the ear and it seems to come from where the power lead goes into a cylindrical housing on the top side of inner housing. Inside it is a copper coil wrapped in a cardboard tube with a foam outer lining(thats toast). Transistor ? anywho anyone have any advice on what might need to be done to make it play baseball games instead of miniature farts ? 
Upon further research it seems the noise is actually coming from another coil that is mounted to the backside of the face of the redio with a square metal housing, three wires. One of which is pink and leads to what looks like a small speaker magnet on the face side next to the light bulb..

Do you have a part # or model # any where on the radio? If so it would help with google to find the info you are looking for. I would also suggest checking out the library since they typically have a bunch of books from around that era. You can also contact the San Diego Auto Musuem. They have a library to pull info from as well. I found all sorts of stuff in there on an extended visit after talking with the staff.
