I should have read this thread through from the beginning. I guess I lean to the K.I.S.S. theory because I sure didn't go to the extent that Phillip did when I rewired the motor on my 15-91 (same motor as the 201-2). Just in case my thoughts and experiences might be of interest, here's the post I made when I did mine.

My machine runs just fine and sews up a pink storm.
Phillip,
Can you post a pic of that dim bulb machine you mentioned? Sounds like an ancient gadget I'd like to have.
