I run a small service workshop for electronics, especially tube amplifiers.
I have received a Marshall JVM410H which emits a pop sound in a non-linear pattern. There may be pop sounds at 40 second intervals or it may take up to 5 minutes before the sound comes. The sound does not depend on the volume controls. The sound can be reminiscent of someone pooping on a microphone. Any suggestions on where to troubleshoot?
