Sometimes it works, sometimes not.  I have to fiddle with the input cable.

How do I replace the input jack on my CODE50?  Does it simply unplug/plug into the PCB?

Where can I get the part and a diagram?

Thanks.

I tried the factory reset. It seems the only thing that did was wipe out my presets. It did absolutely nothing for the noise from the input jack. The noise is like 60 cycle hum on steroids. I've tried four different cables that were dead quiet when plugged into my other amps.
