Peter Wittenberg, K2LRC

We repair and recondition S-line gear and have an extensive Lab with HP / Tektronix and Fluke test gear to provide repairs. We provide professional test data on every unit that goes through my lab. You can see this on my web site. I also sell some S-line gear that I may have from time to time.

We can occasionally have S-line Cabinets and the associated trim rings repaired (holes, etc.). and professionally repainted with the original colors.
