hooternanny Posted July 8, 2014 Share Posted July 8, 2014 Hi All, I was playing the other night and all of a sudden my amp quit working. It lights up but but I get a barely audible sound out of the speakers. I play through a 4X12 slant so I tried the built in 12s first, no improvement. I tried a different guitar and cable to rule them out. The 6l6s and the 12AX7s glow. I run a short board so I disconnected it to make sure it wasn't causing the issue. Any thoughts on what else may cause this issue? Cheers! Chris Quote Link to comment Share on other sites More sharing options...
napynap Posted July 9, 2014 Share Posted July 9, 2014 ... I play through a 4X12 slant... That 4X12 Slant cabinet you mention should be 8ohms to use the single 'A' Speaker OUT. Otherwise I fear you may have blown something in the power amp stage of the SV MKII 212. Quote Link to comment Share on other sites More sharing options...
hooternanny Posted July 9, 2014 Author Share Posted July 9, 2014 Thanks napynap. I rewired the cab to 8ohm before I started using it with the SV. Quote Link to comment Share on other sites More sharing options...
hooternanny Posted July 16, 2014 Author Share Posted July 16, 2014 Update. Problem solved. I discovered that one of the JJ 12AX7 I installed in April died. Not too happy with the JJ's but happy my amp is okay... 1 Quote Link to comment Share on other sites More sharing options...
