Hello everybody. I've got a Situation that I'm trying to find help concerning y buddy's bass head. There is a constant rattle when the head is on. When we opened it, it turned out thetube was rattling. After securing the tube with foam and tape we wentfor another run, the rattle was gone for the most part but the fan was still very audible. Is this normal? Also in the last gig, the head started making very audible noise. It seems like everything is going wrong with this head and it's supremely frustrating. I don't know much about internal electronics so that is just perplexig things. Has anyone else run into a similar issue and have an explanation and or solution? The tubes seem to be functioning fine.

How old is this amp head? Parts tend to loosen when subjected to low end vibrations from sitting on a bass cabinet. Open the amp, and check all components to see if they "rattle". Re- seat all of the tubes?
When tube head components start to fail... they all seem to start failing. Have you ever changed out any tubes? If not, break down and purchase some tubes.
Fan bearings wear out over time. Check the blades to see if they're hitting the fan housing. It may be time to replace the fan.
What do you mean by "the head started making an audible noise?"
Are the tubes squealing?
When transporting Tube amps, they should be handled like fine crystal...free from bumping, dropping, or other rough handling.
