Ethernet cable for turntable?

I may need to rewire the tonearm on a Technics 1200. I had a crazy idea to strip some Ethernet cable I have laying around and use the individual wires for the tonearm. I could also make some headshell leads while I’m at it.

Thoughts?

Hey @onlysleeping, here's what has worked perfectly for me, YMMV.....

Find an old set of earbuds and carefully remove all the wiring. If it has a volume control, just use the wire from that control to the plug as it will still be plenty long. My experience is with Apple earbuds, so it's possible that others may not work as well, but I found those to be copper Litz wires and a fantastic choice for my Nottingham Analogue Studios Spacearm that needed re-wiring. And further good news is that since I don't wear earbuds, it was a free alternative to the prices many are charging for that kind of wiring these days. The advantage of using such fine, hair-like wiring is that the movement of the tonearm is not restricted so you're not causing other problems as @JP has warned about above seconded by Sarge.

A challenge you will face is the removal of the very thin coating of insulation at the ends where you will be soldering your connector pins on the one side and the RCA plugs on the other, unless you are going to a block of some sort but you'll still have to deal with that coating. Some have been successful just using the heat of a soldering iron to melt it off and I suppose that would work although my efforts have been more successful the old-fashion way of stripping it back, which can be done but fair warning, you will need to move very slowly and use a light touch, preferably wearing some magnifiers so you can see when the wire is bare. I "rolled" the wire under a razor blade just slightly to get a weak spot and then remove it with my fingernails. I did fail a few times at first until I got just the right touch, but I had plenty of length to work with, as will you, so it was just a matter of learning the process. It doesn't take much to get it to come off after you create that weak spot, but even the slightest bit of too much pressure on the blade and you're cutting wires and will need to start over. I don't remember exactly what the resistance was right now, but I do remember it having been identical or nearly so to the silver Litz that was in the tonearm originally. I could tell no difference in the sound, and that's the real winner!!!

Good luck, and let us know how you go amigo!
 
I suggest you go to KABUSA and get their kit:

SL1200 Arm Wire Set KAB SuperFlex NEW!!
It comes with a tonarm liner to supress ringing.
Also print out his instructions for the process.
I used a similar kit in my 1200. While I was at it, I replaced the RCA cables with rear-mounted RCA jacks (KAB PC-1200). Now I can experiment with different interconnects.
It was worth the small investment.
The owner (Kevin) can be very helpful if you contact him.

Why not to buy wires from KAB?

If on a budget, I would say try your hand with the earbud wires since they can be free! Those things can be found with most devices that Apple sells (sold, I understand they are no longer including earbuds with their iPods, iPhones etc. etc.) and a lot of others as well....

That said, yeah, Kevin at KAB is the epitome of customer service in my opinion and that would be where I'd go if I didn't have the wires already. Good tip, Armand.....
 
The twisted pairs in some HDMI cables can work in a pinch.
Exactly! HDMI cables are an abundance of good TA cabling. IIRC a single 3 foot HDMI cable contains about 60 feet of leads, including twisted pairs (white/blue included along with red/white) and a life time supply of TA ground leads. :)

Ethernet cable (AKA 'network' cable) OTOH, is not very good choice for tonearms.
 
Shielding isn't something one typically sees on internal arm wiring.

yeah true, not sure what I was thinking but I thought OP was looking to use them as the interconnects, not tonearm wires. This is what I get for posting before finishing my coffee.

Thanks for all the suggestions. I was hoping to use something I already had laying around. If I find earbuds I may give it a go.

I will likely place an order with KAB once I have saved up enough for the fluid damper and a few other things to save on shipping.

I realized I may have gotten ahead of myself - I need to check if the issue is the tonearm wiring or the RCA cable. The problem is no sound in the left channel. After I confirm the problem I’ll figure out what to do next. I plan to meter from the tonearm to the PCB, then RCA to PCB.
 
@onlysleeping, I think you will be happily surprised with the earbud wires should you find some. Also, Tom (@tnsilver) makes another great suggestion and while I have not tried the HDMI wires for tonearms, I have plenty of them hangin' round so next time I'll give those a shot. Thanks Tom.
 
For the future, I would say the fluid damper is worth it!
