Not going to hurt your speakers. I would float the ground with a cheater plug and see if it goes away.
TALK Amplifier Tornado 2.1 ....A BUZZ Sound
This Amp has a buzz sound that is audible a foot away from unit.
The Amp plays and sounds great, but I am concerned that this Buzz can hurt my speakers.
Anyone perhaps has a suggestion how to resolve this buzz...and mainly wonder if I can leave it this way .
Thank You
