Using this thread as an example what is the attraction for new members to old and ancient threads? Yes, I can understand sometimes adding new information to an old thread where it may benefit the overall thread content but I don't see that in the linked thread. Often new members come in and dig out an ancient thread, add a few words and place an old thread at the top of the pile. What's with that? If an oven controller board mystery transformer has not been fixed in close to ten years I would guess the thread is done, well done.
