I have a 66 c10 with a factory am radio in the dash. The radio is all original to the truck. I just got the truck not long ago and when I turn the radio on the dial lights up but I get no sound in the speakers. Everything appears to be plugged in correctly. Can someone tell me what else I can check to find out why the radio has no sound. Is this a radio problem or a speaker problem. Thanks. Chris

It could be either, I don't have much info on trouble shooting though. Someone will get you pointed in the right direction.

The only way to tell for sure is to remove the radio and test it on the bench. There is a tech tip on this. However if you want to try something right away, here is something you can do. Unplug th antenna and insert the bared end of a length of hookup wire into the tiny hole in the antenna socket. If you get some reception with that arrangement, you have an antenna problem.

unplug your speaker wires and plug them into a known good speaker try that before removal of radio if that dont work ive got a original 66 radio that does work or the blockoff plate if you want to go to extreames

Check out the voice coil in that speaker, these early transistor radios had another problem when the voice coil open up and the radio was left on it would short out the output transistor then burn up a fuse resistor first find out if the voice coil is open but don't leave the radio turned on, check it with a VOMA meter ,with a good speaker you should here a "thump" in the speaker when the radio is turned on that would mean your output in the radio is OK, BILL
