When does it make the noise?  Is it volume sensitive (IE, is it louder with the amp turned up)?

hi , the problem happens some times while playing , as soon i hear the pop (more like firecracker sound) i turn the amp off . when i turn it back on the amp acts like nothing happened. if i dont turn the amp off has soon i hear the pop  the loud white noise will appear.


ps : sorry for my bad english

I'm not sure I've dealt with this specific issue myself.  How often does it do this?  Is it every time you use it?  After a few minutes?  Is it repeatable?

Monitor the high voltage rails on the amp to see what happens when the symptom occurs. Always good to start with something that is observable like power voltages.
