For a couple of years, I did basic repair work on the Kenwood TS-930S. My growing family, new home, and increased professional responsibility have made it difficult to continue this activity.
If you have an undiagnosed problem or want comprehensive service, the only person who I am aware of who is both a Kenwood authorized technician and repairs the TS-930S is Clif Holland at AVVID. He has never done any work for me, but I have spoken with him a few times and know others have worked with him. He’s a straight shooter.
