How can I eliminate the electric potential difference between my power supply's negative and ground? Answered
The question is pretty straight forward, I have my fair share with electronics, so I'm not really new.
I have a linear power supply in my shop and only now it has started bothering me that there is like 35V between my psu's negative and ground.
I would normally not care, but since I've gotten into audio and video I found it to be problematic, because every time I connect my psu's negative to my lets say source audios' negative, 4 amps start to flow from my amp to ground trough the thin audio cable I use. I know it's not my source's fault because it's switching psu's negative is shorted to ground.
