    Hey there. I have a Jester Oahu 30 watt class A amp (I think they were based on the old Valco amps). It has a standby switch, but when you switch it to standby before powering down I'm getting a fairly loud "thump." It's not super loud and I have a pretty heavy duty speaker in there (Vintage 30) but I guess I'm wondering if this could potentially be harmful to the amp or speaker. I tried turning down the volume before switching but that doesn't effect the thump. I guess the standby switch is arcing and I should replace it with one with a higher voltage rating, but is this necessary or should I just keep playing and not worry about it?
    Thanks!

    Turn off the power first, then the standby.

    Isn't this just a carbon build up on the switch? Get a new switch.
