Reply To: Gu50 signal path

[Sondre]

Ok, signal wire is connected as pr instructions in video, so no ground connection in signal path. I will test this and see what happens. If it doesnt work I’ll add a wire straight from the RCA to the star ground point as would be the closest match to using the mains ground. Btw, one of my preamps have dual isolated configuration, so even with household mains ground this one would not complete the ground circuit as is your intention.
