Hello all,

I recently bought a Purepower 2000. The unit buzzes loudly at about 70% load (buzzing is softer at lower loads).
The buzz can also be heard through the speakers and is very annoying.
If I disconnect the mains cable to the Purepower, the noise reduces considerably.
Is this due to the charging circuit?
