Thanks, sorry about the PM....I'll update my prefs. There are two little contacts on the sides of the clickie which I assume provide contact with the tube, and the larger contacts on the bottom of the clickie. Is this what you mean by "the spring that's attached to the Garrity clickie"? Sorry to be so dense about this, but am I correct in saying that you have no coiled spring whatsoever in your setup? Thanks....Rick
