haha, good eye. No, it's a (I think) 20+ year old Electraglide power cord. The first power cord I ever bought. For some reason it gets pressed into duty at times like this. I have a Transparent PIMM that I may move from my router/nas drive to power this. GPA just included a standard beldin (again I think) cord.
The owners manual says when you press the round PSU button it goes from Auto to full AC isolation, so power cords may not matter at all here.
John, I thought the same about power cords for turntable power supplies. I was very surprised when I heard differences, and the best power cord of the ones I tried was the one that was supplied with the power supply as stock. Dedicated circuit and everything. I made a video to document the differences and sent it to DDK and the difference is were audible over an iPhone video. It is worth trying different power cords for the turntable power supply.
