Any old line auto parts store as NAPA should have HV wire, tell them you want copper wire not carbon and should have spark plug connectors either 90 deg or straight and boots. Weather that will work for you I'm not sure. Most people just wrap the copper wire around the terminal end on the tube a few times and then over wrap with some solid core copper wire, kind of like what you did in Scouts when you whipped the end of a rope. Solder will not really work that well on the tungsten wire coming out of the tube.
