Turntable Interference (power problem? please help!) - Page 2

Thanks for the picture / diagram.

To what was he soldering the outer braid? I've never seen the guts of a modern turntable before, so I wonder how difficult it was to solder the cable inside. I don't s'pose you have a sequence of pictures detailing the whole process...?

No, he didn't soldier anything to the turntable. He just soldiered plugs onto some coax cable.

Here's a diagram I made to help:


Now of course, he didn't soldier them to the outside of the plug where the lines I drew point - but on the inside, on the reverse side of the plug that you can't see.

I hope this helps!

Oh, okay, so really it was just a matter of making some new cables. Most turntables have the coaxial cables wired/soldered directly to the tonearm instead of having female RCA-type outputs on the back. It's probably nice to have the option of just throwing on a different set of cables.

Ah, well if your turntable has the cables wired directly to the turntable then they are probably at least coax. The cables that came with my turntable were just cheap chinese wire, like the kind used to makes the cords in $10 headphones. That's why they picked up so much interference.

If you think RG59 is "heavily shielded", you should check out RG6 quad.

heh, well I'm not sure what mine is. That picture is just what I found on wikipedia, its not mine.

All I know about mine is that I can turn the volume on the amp all the way up without hearing any interference whatsoever.

EDIT: well, when the volume gets to its highest, I can start to hear a VERY faint amount of the interference I mentioned... but I could never listen that loud. I would surely blow out my headphones if I tried to play any audio with the volume that high.

There are interconnects that are better for audio transfer (better conductor, shield, construction, etc.), and if you stick around this website long enough, you'll probably be interested in some. Any decent cable should avoid interference and hum, but better cables will give you improved frequency response. Obviously uber-expensive cables aren't really worthwhile for most setups; my personal limit is ~$35 for a pair of LC-1s from Blue Jeans Cable.

But let's not turn this into a cable discussion.
