Please RTF post. The OP is correct in that racing wire is solid conductor, not carbon.

Not sure if the racing wire is steel or copper. Still have a chunk in the garage somewhere. Mostly good for wrecking radio reception. IMO, the difference between OFC and ETP copper doesn't amount to a hill of beans.

The red wire I posted earlier... not sure it is truly 0 ohm wire, I'd have to ping the company. But racing wire does tout 0 ohms, the problem is finding some racing spark plug wire at a reasonable price

Spark plug wire for tubes with a top cap?
My bad. I should have read more closely. If it's truly low resistance wire, it should work. One of the reviews said it melted in one persons use so keep it away from the tubes. Also, it's gonna be pretty fat - it wouldn't fit into any of the plate caps I use.

You can get heater cord at any hardware store by the foot. I paid 20 cents/foot for mine. Just saying...

This was all a passing thought I had not liking the dinky wire I see coming off the 807 on my breadboard. I like the idea of having the harness to the cap be very flexible and with very thick insulation and look professional.

I wire up motorcycle accessories in my riding club using braided PET loom in many cool colors and snakeskin patterns. So a bit of that loom around the heater cord might be just the ticket to make it look cool and more shock proof!

Spark plug wire is just too specialized for EMI, if this subject ever comes up again here.

Belden test probe wire is perfect. It reminds me of spark plug wire but with somewhat smaller diameter insulation, so it should work with pretty much any plate cap. It is cheap and it is definitely not made of anything weird to enhance its performance as a spark plug wire that will cause problems in your application.

I mean, give spark plug wire a shot if you want to and let us know how it goes, but test probe wire will definitely give you what you want and isn't expensive.

I'd use 10KV silicone test lead wire - I may still have some white 40KV silicone CRT wire that would look good with the ceramic caps...

Good idea Tom! Amazon has 30KV white, pretty cheap too. It would match the ceramic caps and should be pretty safe for curious people that just have to touch everything. This one is about 4.5 mm .18 inch, it should make it into the cap.

I have some alpha wire 60kV 12ga. Magflex.

It's a bit overkill though! And only available in 30m reels.

But it is 100% copper.
