Boss RC2 high pitched noise.

I have an Rc2 which is the last of 5 pedals on my board. With my usual power supply it whines like a busted milk float,but if I use a different power supply for this pedal alone all is well. Any suggestions other than using two power supplies?

You need to either get something like the BBE SupaCharger or the Voodoo Labs PP2. Any pedal utilising digital components need all the power available to function properly. Of course using a separate is another option.
