roc pro wows

i have had my roc pro 1000 for about 15 years and love the sound, but lately it has been cutting out, its like the power leaves. you can still here the guitar but at a much lower and static volume. it does not affect the clean, just wondering if anyone knows what the problem may be? i have change the tube and cleaned all the pots and it still does it.
