A few months ago my GK MB115-II spent a week in my old bands equipment truck and got wet. (The "waterproof" bed cover leaked.) I let it dry out for a week before using it again and it was fine. I turned it on after not using it for a week I noticed a clicking sound along with the power light flickering when it happens. It happens at random intervals (probably when too much power is being drawn) but otherwise it functions just fine. I pulled the amp out of the cabinet to take a look and can't see anything out of the ordinary. I'm hoping this isn't permanent damage (it's my only amp.) Thanks in advance.
