My tuner is also dead. It would work for awhile until it got warmed up, then get static and would not tune. Mine also looks like it had some rust. I was thinking it looked like it was not properly bathed in the final stages of production. I've seen this before where the acidic nature of the flowing process can lead to corrosion if not properly washed. Anyway, I also thought I had read about some sort of problem with an opamp, but no one seems to remember.
