Hi Malte
I have a P6 that I have fitted a KIWISIX board and psu to.
I have followed Murray`s grounding setup that involves
grounding various componants on the voice board, effects board
and output to dedicated groundings on the psu board.
The kit also includes 2x ferrite ring kits to fit to the interface
scanning lines (blue cables from front panel) and the keybaord
scanning lines.
My P6 is quiet but if I turn up the volume to max with output set to
HI and attenuator to +10 I can hear the scanning lines as a high
pitched white noise like whine.
This could be what you are hearing ,bearing in mind the output
is cranked up to max.
