For sale we have a Mcintosh MX-130 A/V Tuner Preamp in very good condition. We installed new glass and trim on this unit, made small repairs to the bottom rail that the glass sits in, installed all new bulbs, and went through and cleaned and tested the preamp. It's a great piece with a nice Tuner, very good Phono preamp and loads of inputs. The original remote is included, and while it's missing the battery cover and is scratched up a bit, it still works as it should. As mentioned, The glass is new, all the knobs are in like new condition, the back panel is in excellent condition with all plugs in perfect shape. The top shroud is in good to very good shape. There are some light scuffs with some paint scratches. There are no dents on the cover. We ran the preamp in our house system for about a month and really enjoyed it. We are located in New Jersey and have some great radio stations, so we mostly used the Tuner section, which performed extremely well. We also listened to a lot of vinyl on it and we were impressed with the Phono preamp. Overall a great looking, and sounding preamp/processor.
