Need some well screened co-ax 'phono' cable. A quick look at CPC shows
only the usual lapped screen variety. Which I already have.

Basically, I need to run an unbalanced circuit close to some mains
lighting wiring which has a dimmer. And the stuff I have is letting in
buzz.

Tried some RG 59 I have lying around which eliminates the buzz - but I
don't have enough and would prefer a more flexible audio cable.

Happy to buy a reel. It will all get used - eventually.

I'm guessing a braided screen plus perhaps a conductive plastic layer
would be ideal?

RG58 can be more flexible.

One of that problems I've had with microphone cables of the unbalanced kind
is not hum, but crackle. It sounds like static as if there are minute
discharges as the cable is moved or bent.

The cable is quite old now, but I'm sure it never used to do this.

Mics are a different kettle of fish as the level from them can be very
low. More akin to a pickup cartridge. IMHO, mics are better balanced,
unless the cable run is very short.

But my problem is at standard domestic line level.

** Common problem with high impedance mics, electric guitars and piezo transducers. The noises are due to electric charge created by bending the internal insulation and/or friction between it and the ground screen.

Some plastics are more prone that others, Teflon is a good one.


The cable is quite old now, but I'm sure it never used to do this.


** Bet it did.

**Find some second hand Monster Interlink 400. Very well shielded.
Individual wires are plastic coated, so corrosion is a non-event. Best
of all, because it is an 'audiophile' cable and no longer flavour of the
month (it's about 20 years old), it will be very cheap. Maybe even free.
And, despite the fact it is (or was) an 'audiophile' product, quality is
very high. This is the stuff I use now:

Obviously, this is retail pricing, but you get the idea. Connectors are
hand soldered(!) and cable quality is very impressive, with PE insulated
centre conductor, with braid and foil shield. I just cut to length, if
required.

Er not quite Trev.
New
http://www.russandrews.com/kcag-inte...00/?src=google
Used
http://www.hifi-forsale.co.uk/morein...=31302&offset=
£510 for a pair of 20" phono interconnects which new have no
attenuation but used have 14dB attenuation. Eh? Then they want £100 to
'burn in' the cables...........

If you buy those you do need locking up!

The Monster's you quoted above do appear on fleabay around £10 but are
still available new (!!) for north of £40 for a 2m pair, so maybe not
so cheap?

**Which is precisely why I suggested second hand is the way to go. The
cable, itself, is particularly robust. 30 year old stuff will work just
fine. Most of my stocks I acquired for free.

Maybe. FWIW I bought one of the 'Shark' types of coax from them ages ago
which had very thick braided screening with loads of strands. Hence much
more copper thickness than usual. Seems OK here, but is fairly large
diameter so may not be flexible enough for you. Afraid I can't recall the
part number as I got it years ago.
