Brian and Mark-I did not expect there to be this kind of response to B & O gear. I don't know if you are fans, or just found your 'tables along the way while looking for other things, but appreciate your help.
Brian, The B & O 6002 has what is sometimes called magnetic drive and a very different technology than the 4002 uses. The TX motor will, unfortunately, not fit in the 4002. Regardless, I might be interested in the 6002. Does it work?
Mark, I appreciate your offer and while the motor will not work in my 4002, I might take you up on your offer to poke around in the 5500. Do either of yours work?
