Reply To: Gu50 signal path

[Sondre]

Good morning Charles.

That was a clarifycation. Thank you. But please try to understand me now. According build video for mounting small parts we install phono socket with the small plastic shims that isolate the phono socket mass from chassis effectivly isolating phono signal ground from chassis ground. Then we prepare signal wire in a following video, both to the gu50 from driver board, and to the phono socket. BOTH wires we are instructed to cut shield/ground in one end. This is ok for the gu50 side as the tube has ground through pin 7. But the wire between phono socket and driver board need to carry both negative and positive signal, and this is not possible per instructions when we cut shield/ground on one end? How does the prototype get signal ground? Have you removed the spacer that isolate the phono socket mass? Or as I said in my initial post, if I am getting ahead of myself, and you have planned to put in a separate wire to carry signal ground from phono socket to chassis?
