    Hey all

    I have a question about a tube amp. Its a sovtek.

    At high volumes, the light that illuminates the standby switch gently pulsates. Is this an issue?

    Thanks

    I dont mind it. I cant imagine that it is any indication of the amp being pushed too hard, but was curious.

    Loose connection being aggravated by vibration?

    It's pretty common. The light is powered by the 6.3voltAC circuit for the tube heaters. The sockets are notorious for not making great contact. Nothing to worry about.
