Hi all,
has anyone ever had trouble with the grounding of the K5 Pro? For some reason the PSU of my unit loads the ground shell with up to 100 V. The resistance is high enough so that I only end up with roughly 130 uA, as far as my DMM can be trusted. I can definately feel a tingling when I brush my finger over the metal housing, though. Sometimes I even get a light zap when I touch the shell of the 1/4" connector. And another thing: With the device turned off (PSU still connected) I hear a loud buzzing with my R70X connected. As soon as I power the device on, the noise disappears.
I have been told that the high voltage on the ground shell is due to the loaded y capacitors inside such two-poled power supplies. So, everything normal here?
Would you recommend to try another type of PSU?
Or just bridge the whole thing to earth?
Regards
