CB has no sound

[wrecking-crew]

Well, very little. I have to have the speaker against my head to hear it. Both external and internal speakers.
What could cause this? It has happened with all 4 CBs I have tried except a Mirage, but that blew the fuse.

CBs : '94 Cobra 29, '92 Cobra 25, and a Cobra 29 'nightwatch'. The Mirage blew my only 2a fuse, so I'd rather not use it.

Or better yet, should I just buy a new one?

Yeah. I got a bad mic. Tried another one and it worked fine. One of the connectors are corroded.
