    Hey TB I have an Ampeg SVT PR410 hlf cabinet that makes a very obvious crackle/staticky sound only when I turn the tweeter on, and the sound goes completely away if I dial it all the way down. I am not a “technician” by any means so any advice on what to do next would be appreciated. I’ve seen similar questions here before but didn’t quite get the answers I was looking for. And they don’t make these any more to boot. Has anyone had this experience? What gives? Thanks!

    Yeah I checked all that and it still persists, it definitely only happens when I turn the attenuator dial up from basically off to barely on and any setting up from there. Thanks btw

    Blown tweet

    Bad crossover board

    Or both.

    Plastic connector on ampeg boards is known to burn up
