Yep, SVOJohn is correct - Mucho apologies that I got it wrong!!!! I guess "Tweecer" to me has always just been a generic term and I hadn't used this thing in a couple years...

Forget anything I said about "tweecer" - this is an "EEC-Tuner" (just like it says on the circuit board, duh!) - more info available here...

Thanks again John!
