Mint Condition, 1-rack space preamp, audiophile quality preamp with highest quality op amp, caps, connector controls, and circuit board. 2 aux ins, 2 tape inputs/dubbing, and processor loop, monitor switch L/R mono reverse switchable/defeat tone controls, Nice Style.
Although these Crowns are excellent preamps they are not significantly different than an APT (which actually has a better phono pre) or an Adcom. Those two are both 2 rackspaces though.
