Hello my question is , who is familiar with a problem with Line 6 Spider Valve MK100 , I can use it for 30 minutes and then it shuts off After this it continues to do this in a kind of loop The tubes are good and tested , the bias is also good It's just playing for 30 minutes and boom then it shuts off and then starts up again after a few seconds It's a weird problem Who might know what the problem is and or has a solution for it
