I have an original Grace 101 mic preamp for sale, comes with the power adapter. It has an amazing clean detailed sound, I'm downsizing my gear so it's up for sale. The front lettering is wearing off a little bit and the chrome is peeling a tiny bit to the right of the gain knob, other than that it makes anything sound awesome through it. Both XLR and 1/4" input/output. $340 shipped.
