I have been looking for a preamp for quite sometime now Lee
The 1000 is not a preamp on its own, it's an expander and noise reduction unit.
Maybe you're thinking of the 4000, which has the autocorrelator in it too.
If you're looking for one of those, I've got a couple of them, but they're very finicky. Nice when working but they suffer from a motherboard has solder issues. I'd be afraid of shipping one unless you are capable of resoldering the motherboards if it developed trouble.
They do sound nice when working though! What city are you in?
