Adam,

feel free to publish this information elsewhere. After we discovered the
problems we took a look at the specs of the power supplies and found that
even in the data sheets ripple and noise of up to 240 mV are specified.
Hence, it is not surprising.
I will also add the information to the DIY page.

Best wishes
Dieter Doepfer
