Sound comes and goes on the drive channel, and there is a strange crackling on the clean channel. i dont know if its the tubes, the speaker, or electronics.

Using a common lead pencil, gently tap on the smaller tubes in the unit, listening for noises and crackling to change and the drive channel changes.

It is normal to get a slight twang when doing this from the microphonics of the tubes, however, the crackling and up and down volume points to a bad tube.
