I would very much like to find out what the problem is with the cases where people have reported this issue. I haven't been able to replicate it myself, even with a unit that apparently suffers from the problem in it's original installation. Like I said in the other thread, for me they either work correctly or not at all.

The RF module used in the kits is different from the original empeg tuners, because the manufacturers stopped making the old ones, but the replacement is supposed to be completely compatible just more sensitive. That may indeed be part of the problem, I suppose.

The rest of the electronics are pretty much identical to the empeg design, although there were a few minor changes to make it all through-hole. As I can't reproduce the symptoms, though, I can't really test to see if these changes are the cause of the problem, which appears to be fairly rare. If anyone has any ideas I can test I'm quite happy to do so.
