Hello, I recently acquired a Cello Performance supply II and amplifier. Unfortunately, the cello performance supply emits a constant static noise from the supply when turned on. It is currently wired for North America voltage. How can I check it's wired for 120V (as opposed to 110V). I read in another post that the maybe due to insufficient voltage. I have attached a picture of the supply in question.
Thank you
Thank you
I can only tell you this: I've got a Cello Encore double mono amp, and when I earth it, it rumbles. If I don't plug the earth, then it's ok... I'm living in France, the Cello is 220V made, and we have a 235VAC mains. Of course, I don't use the earth plug.
Oh, I forgot: the Encore circuit is about the same than the Performance, except the power (!) and the external PSU.
