Default Shielded cables - success

Got a few projects on the go at the same time (headphone amp/Buffer and Aikido), and always had issues with the noise from the wire the precedes that volume pot to the grid.

Just tried some coaxial cable used for the tv.

The quietest cable I've tried. Dead silent .. even when touching the wire while it's playing.

I grounded the outer shield just at one end.

Cheap and effective solution.

Glad to hear!

I love using RF cable for interconnects... RG8/M (minifoam) is awesome and just as or more flexible than the "pro" stuff.

Cheers!

Minifoam... .242" diameter. Not the .408" stuff you can use a 2' chunk as a billyclub

I've used RG-174 coax for audio with great results.

Good to know that there are more flexible cables.

Think mine is the standard RG175 which is a little rigid to say the least.


Think I'll have to look for some flexible options as you suggested. Also I couldn't solder anything to the shield of this cable.

Could you solder wire to the shield of the other cables mentioned??

I just got some of this wire from ebay . It is a little stiff, in an easy to work and route kind of way, but it is pretty small diameter and works well. Easy to solder without melting! His other teflon coated wire is good too.

The braid on the stuff I'm using for signal wiring solders no problem; it's RG-174 IIRC. You have to apply some heat to it with the iron, since it's got a lot of thermal mass. I also use a little flux when soldering the shield/braid. I twist the braid into a little pigtail and then solder to it.

Looks like RG-316 or so. Handy stuff.
