Old thread but related to the RVC from china.

Hmm, interesting. Never had any issues with noise with mine.
The noise is very low, you'd be doing well to be able to hear its effect. Their only criticism seems to be that it is not perfect. But it's a hundred bucks from China so not really a big deal.

Agreed, why so many mains harmonics I don't know.
The psu arrangement is very traditional, transformer, bridge rectifier, smoothing cap then into two chip regulators.
I'm selling my one on ebay as we speak. I found it erring on the bright side in end so off she goes.

I must try a dcb1 build Ollie but I think I've let my passive khozmo put me off a bit.
Need to try one in my system somehow before I start shelling out on bits.
