    Good Morning all!

    I am noticing my Ampeg SVT VR is vibrating alot during playing. I am setting the volume to 11 o'clock bridged.

    Is this normal? Can this be damaging the amp?

    Thanks :)

    Does it vibrate when it's not on top of the cab? If so, I'd say there's something wrong, though I wouldn't have a clue what could cause it vibrating since it doesn't produce any sound on its own without a cab.

    Well that's a very loud setting, but usually I don't have any problems with vibrations even at loud settings. Maybe go around with a screwdriver and see if anything needs tightening.

    Yes, something vibrating can damage the amp. It is best to find out what is causing the problem.

    I would first try to isolate where the vibration is coming from. Don't put the amp on the cab. Is the vibration from the cab or the amp.

    Assuming it is coming from the amp, play something that causes the buzzing while someone else works at the amp to isolate where the noise is coming from. Apply pressure in-turn to the front grille frame, different places on the back metal grille, and the handles. Make sure that the power and pre-amp chassis mounting screws and bolts are tight.

    The next step involves removing the back grille and checking out the inside of the amp. The most suspect source of noise is the retainer spring assembly that hold the power tubes in place. Sometimes the springs vibrate against the tubes. One solution is to slide a high temperature rubber tubing (sometimes available at hobby stores) over the springs.
