Looking for shielded hookup wire for tube preamp
I'm building Tube Line/Phono preamp combo and can't seem to settle on what shielded wire to buy for final assembly. Currently whole project is mounted on prototype chassis made of masonite board.
All transformers are remotely fitted into aluminum enclosure and connecting with preamp via shielded 18 conductor cable.
I used old (70's) shielded stereo interconnect cable for hookup. Phono input wires are placed inside of grounded shielding tube.
I got all hum figured out in the line stage and it is totally quiet but phono is stubborn.
Looks like I may have to build metal dividers around phono PCB if amy hum is still there after everything is assembled into aluminum chassis.
I'd like to use single shielded wire for line level signal and 2 conductor shielded wire for Phono signal.
I'd prefer combination of thin diameter and low capacitance if such exist.
Would 24g be what I should be looking for?
Thanks for your help
Below are pics of the transformer box completed. There are 2 relays. Main is controlled by power switch and second is controlled by source selector when Phono is selected. Small transformer in the middle is for remote control volume board. Dabs of silicone aren't holding anything, just for redundant protection. Last picture shows connectors that will be at the preamp end of metal chassis.
