The only important thing about unbalanced audio cable is that 
it the shield has low DC resistance. The calls for a decent 
copper braid shield. Mini coax like RG176 works fine. So does 
ordinary RG58. But remember, I said COPPER BRAID, NOT 
ALUMINUM FOIL!  

AND -- resistance isn't even that important if you follow the 
simple instructions on bonding all the chassis together with 
short pieces of copper. I use either the braid stripped from 
coax (equivalent to #12 - #10) or an equivalent piece of THHN 
(house wire). 

To understand all this, see the Ham Interfacing Power Point 
and the chapter on solving problems in the shack in my RFI 
Tutorial.
