Don't know about the capacitance Jim. I'll need to measure it. A few inches haven't made a lot of difference in the high end of the audio spectrum though, and most of my circuits terminate in 100 K ohms or less.
I was trying to think of a need for a terminated delay line type thing where as the inside wire is grounded and the outside wrap is the hot wire. I just don't have a need for it. HIHI CU, John, WA5BXO
