[Motorola] Motorola Mocat Model CB1124

[Joe Walden]

Hello,from Joe w5jdy in Okla...   I have a Motorola Mocat Model CB1124.  It has an intermittent crackling sound like a leaky transistor (maybe) in the pre-audio circuit.   The noise is still there when  the antenna is disconnected and can be controled up or down by using the volume control.  Can someone help me with a schematic ro a solution.  I will gladly compensate.  Joe
