Was wondering if anyone could help me out with this problem. I bought a roadster not a week ago and it has already gone through two rectifier tubes and two fuses. I'm just about ready to send it back, and get a mark IV, what I wanted in the first place (curses to Mesa for discontinuing them). The amp shows no signs of trouble before these things happen, they just come out of nowhere. Tests of the power tubes look good. Any ideas would be greatly appreciated.
