Thanks Joel, Justin, & Tim,
I'll take you advice and pick up a new set of W7TDC's. Yeah, I could
probably just replace the one, but hey, couldn't hurt. Besides, that'll
leave me with three spares just in case. You can never have enough spare
parts....
I was mostly worried about future breakages, but I guess I must have gotten
a bum plug. Or it was dropped. Either way, it seems worth it to stick with
the them.
Thanks for clearing the air for me!
I love this list,
Don Preston
