Tube Head Rattle

    I have a Mesa 400+ head and the tubes rattle when I put it on top of my cabinet and play. I don't ever recall this happening before. I've had the head for about 6 years. Does anyone know if maybe some tubes could be loose or something? Has anyone evr come across this before? Maybe it's always done that and I just never noticed. It's bad enough that I'm afraid it's ruining something inside the head. Any ideas?

    Mine does it too! :)

    I've only had it for a few weeks now but...I don't notice it when I'm practicing with the band, and I'll let you know if I notice it when onstage.

    I brought the amp home from our practice room with my SB112 and have it set up in my apartment...and play at low volume and that forest of tubes does rattle a bit. It doesn't sound like anythings loose or bad, just that the vibration from the cab is moving the tube 'innards' a bit...sorta like a lightbulb when y' shake it.

    I have a feeling that it always goes on, but you can't hear it when at real volume and not polite apartment volume.

    I used to put a beach towel underneath my M-Pulse 600 until I got a rack for it. It's probably rattling because of the cab, try to prop it on something that absorbs vibrations.

    Wouldn't all the ratttling be bad for the tubes, shortening the life or something?

    I'd put something under it (ie. Towel or foam) or put it in a rack.

    I use a Gramma pad under mine. Or, I don't put the head on the cab.

    Mine does it too, I put a big old blanket under it and it no longer rattles. But one of those Gramma pads would probably be perfect!

    to me one of the major advantages of having a seperate head is getting the electronics away from the vibrations of a cab - I would do what it took to take advantage of that.
