I have an old President John Q CB. It seems to work ok, but after a while I lose all sound. i initially thought it was a short in the speaker, but those connections look ok to me. I would like to get it working again if at all possible. Basically, when I first turn it on, it is fine and after about a minute all sound is gone. The meter still registers a signal just nothing is coming from the speaker...

Anyone here know what I should look at? I don't know a lot about electronics, but figured there might be some answers here that I could try. Or, if anyone wants to service it for me, let me know and we can work somthing out.

Thanks!
