After reading your plea for the 4th time I finally went digging. I think I found one: Veglia Te625, bullet connector with porcelin surround, used. Measures 1.1Kohms at room temp., 600 ohms dipped in hot tap water. PM your address and I'll send it to you. If it works, send me $20. If not, send it back. How's that for unobtainium?
