72 Factory Radio fix?
Should be able to hear a tiny thumpin the speaker at power-on.
Fuse OK?
Hi:
Everyone has given some good suggestions. If you've checked your radio fuse or can definitely assure yourself that the radio is getting power, listen carefully for a little thump or a pop when you turn the radio on. If your not hearing this... there's an issue with the radio itself.
If you hear the pop, see if you can get an el-cheapo antenna and plug it into the radio. Tune it to the strongest station in your area and se if you can get your radio to play. If not, or if there's no pop, time to pull the radio.
I wish I could offer some suggestions on this, but unless your car is a '69 non-AC or older car, I can't offer suggestions on this and need help on the removal process myself!
Once the radio is out... there's a few things to consider. My guess on a non-playing radio is going to be the output transistor. You also have a radio with 40+ year old capacitors. All the electrolytic caps should be replaced. There's generally a 20% tolerance on these, so regardless of what anyone tells you, you'll be able to get values that are reasonably close to the originals. Don't worry about the ceramic caps. They **generally** don't fail.
If you're a little bit electronically savvy, this isn't tough work. I replaced all the caps and a failed tube in the radio on my other classic car.(Your radio is all transistors). If you're not, you may wish to check out some antique auto radio repair places.
Good Luck!
