I have a Bassman 135 head that has set in a closet for 8-9 years, I pulled it out and it does seem to have much power. It also sounds very distorted. I have ordered new SoVTEK 6L6's and Electro-Harmonix 12AT7 and 12AX7's along with new sockets for the 6L6's just to be on the safe side. Does anyone know what else maybe going on that a guy can do himself to try to fix this. I live in the sticks there is no music store within an hours drive.
