Well, as it turned out having the oven available for use became more important than cost. So Since the valve was available in town and the t-cpl not, I got the whole valve and replaced it. Works fine now. Looking at the valves while they were outside the range, it appears that the t-cpl is a cap tube, and although it may be unscrewed from the valve body, it's probably not wise. It does not look like the image you guys found. Thanks for the manual, It will come in handy in the future. This particular range is quite old: bad for getting parts, but good in that there is no electronics in it - all tubes, valves, and pilots
Thanks for the help all.
