I had a problem less than a year ago. I heard a light popping sound, then another then no sound. The amp was repaired under warranty. I was setting up to record. I turned the amp on, tuned up while I wanted for the tubes to warm up and when I brought the amp out of standby I heard that familiar pop. Kind of like a lightbulb popping. I have had tube amps in the past and never had to replace tubes so regularly. Is this an issue with this model Marshall?
Hello Kerry,
We have not had any issues with this model, you may have been unlucky with one of the new power valves, we would recommend that you have it looked at by an engineer.
Kind Regards
Marshall Support
