On friday as I was about to practice, I turned on my LINE 6 MKII valve head and a purple/blue wave of electricity rolled over everything metal inside the head. I had it plugged into a furman surge bar as well as my other gear. everything else works fine but now my amp has no sound at all and all the power tubes appear to have burn holes through the tops where the springs touch the glass! I have no clue what to do from here and suggestions or help? I can give more detail if needed
