I had an email exchange concerning the problems I was having. In the end, I repaired it myself, but he definitely sounds like he knows his stuff. He also seemed very willing to help me out.
Ken is great at repairing anything that has to do with sega! His work shop setup is perfect! He has a beautiful setup there! If you have any problems seek his help he is def the best!
just posting my experience with Ken Westerfield. Ken relly knows his shit and has worked on a Naomi 1, Naomi 2 and 3.17 net dimm for me and has done a fantastic job. Very highly recommended even though everyone posted pretty much the same idea of my post. Just wanted to put that out that there
