I designed a cap using alternate wires in a telephone cable with lots 
of pairs in it. I don't remember the exact number of wires in the 
piece I used (think it was around 30  i.e. 15 pairs). I obtained 
around 500pF for a foot length. Details are in a post of mine made to 
the list about mid last year. Not a great cap because the insulation 
was PVC but it did work OK. I tested it to 18kVDC.
