Hi
i have a sound king skak20ra guitar practice amp
worked fine for ages, but then i plugged a mic jack plug in wrong hole and
all it does is make a fairly loud buzz now.All fuses are ok.
Does anyone have any idea what it could be and if i could repair it myself,
I have fairly limited electronic experience but can solder ok, pcd looks
pretty basic if it was just a case of soldering a new cap or whatever
hope one of you bright people out there can help

cheers
Dave
