Hi,
If I plug the Control-RRC into a 120V outlet using the supplied power supply, I hear a 60Hz hum and some noise in my headphones. This is with no other connections present on the device. When I touch the box the unit is grounded and the hum does away. When everything else is connected, touching metal (Bencher paddle, TS-480 metal tuning knob, Control-RRC chassis) also makes the hum go away. Do you recommend installing a bypass capacitor somewhere?
Thanks,
