The McIntosh C28 is a solid state vintage preamplifier from around 1970. It has a backlit glass faceplate, large polished control knobs and push-buttons with LEDs. Controls include an input selector, volume and balance, plus tone controls with individual left and right channel adjustment.
This unit is in original condition with all original parts. Its controls have been cleaned and the oxidized rear panel jacks detailed. All features have been tested and work.
The paint is free of deep scratches, rust and wear. The glass has a textured strip along the top and bottom where the original spacing tape under the frame has deteriorated. A small section of paint has lifted under the mode selector control and formed a small bubble.
