I have L-09ms (see sig line). Right now my Citation 16 is at St. Louis Computronics being gone over, and it will get whatever it needs up to and including a full restoration. When I pick it up, the L-09Ms are getting dropped off for the same treatment. They sound fine and are immaculate, but I'll leave any real assessment of their health to the professionals. Since I got into the Citation and the Kenwoods pretty cheaply(at least compared to ebay pricing) I definitely don't intend to scrimp on maintenance, they're too nice to let the magic smoke out of!
