REV 2 buzzing noise while powered off?

[lefthandshakes]

Hello all!

My Prophet REV 2 is making a buzzing noise while powered off and plugged into the wall outlet. If I unplug the IEC cord from the back, the buzz goes away. If I turn the synth on, the buzz becomes significantly quieter but will still be there. I don't know enough about electronics to know what this could be. Any ideas? The noise itself I can live with, as it's not all too loud. I just want to make sure my REV 2 isn't slowly dying in front of me.

Thanks!

Buzzing through the audio out or something in the unit itself?
Either way, probably best to contact support.

Not from the audio out. I believe its coming from the power supply unit as I can hear the sound coming out from the right side of the keybed.
