a little bit OT - rewiring a tonearm
For the youngsters, a tone arm is what you grandaddy use to hold a cartridge to read music represented by grooves in a plastic disc in the last
millenniuim.
Anyways, I may need t o rewire a tonearm so question is - are the pairs of wires for a channel (+ and -) twisted together or not?
re: twisted pair: Twisted pair cabling is a type of wiring in which two conductors (the forward and return conductors of a single circuit) are twisted
together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from
unshielded twisted pair (UTP) cables, and crosstalk between neighboring pairs. It was invented by Alexander Graham Bell and he was granted US patent
244,426 Telephone-circuit for the invention in 1881.

I'll check 1 of my dead Technics later, but i'm 99% sure they are twisted together inside the tone arm.
