Question about Cobra 29 LTD CB Radio
Have you tried to check the audio as it is coming off of the detector right before it enters the first audio amplifier? you can check this with an oscilloscope and then trace the signal through the stages of amplification the signal should get bigger. I think that you may have blown the final audio output amp. and what you are gearing is pre-driver audio through a leakage path. This is just a hypothesis, but I have seen this happen before.
