AM/FM Radio problem
 

I have an am/fm radio with a multiplex unit and an 8 track in my 68 GTO. The 8 track works well and will play loud. The problem that I have is that I can barely hear the radio. I know that the radio gets signal because I hear some static and occasionally very quiet reception. It has a power antenna. Any suggestions or ideas on how this can be resolved would be appreciated.

Sounds like a power transistor is bas in the radio. I had an AM Delco radio that used to work well but now you can barely hear it.
