This Adcom GTP 450 Preamp with AM/FM tuner is in very good physical condition. The faceplate shows very little wear as well as the sides, bottom and back. The top plate has some scuffs and scratches as well as some "feet" marks from a unit that was sitting on top of it. The unit has been cleaned, tested and functions as it should.

The Adcom GPT-450 is a worthy member of the 1980’s series that put Adcom at the forefront of quality affordable gear. It’s warmness should be noted when pairing with amplifiers. Thus, it is best matched with a solid-state amplifier that is dryer and more technical. Musical amplifiers may exaggerate the warmness especially to those who favor jazz or acoustic popular music. For those with an Adcom amplifier, it is an excellent match that brings out a power-based sound touched with a warm cozy tint.
