Hi sleepwalker65- So I attach the black ground wire from the tt to the preamp chassis as normal. Then, on the preamp end of the phono cables I cut the shield off and do not solder to anything. But on the tt end, I twist and solder each shield together and run it to the origin of the black ground wire and solder it there. Is that correct? Thanks 🙏🏽 Kurt
Phono cable build question
I’m replacing the phono cables on my Technics 1200 and have decided to use cable that has two conductors and is shielded. My question is what do I do with the shield?
When making regular interconnects with shielded cable, I normally solder the shield to the negative conductor and only on the source side of the cable. Do I do the same with phono cables? I thought maybe I might instead solder the ground wire to the shield, not to negative, and also have a separate traditional ground wire go to the preamp ground terminal.

sleepwalker65 The use of twisted pair cable with a separate shield both provides continuity of shielding for both signal-bearing conductors of each channel, and phono stage chassis ground for the tonearm.Whatever works for you is fine, of course, but I'd never wire a phono cable as you've suggested, and didn't even when I used a single-ended phono connection. |
