The unit is in very good physical condition, and in perfect working order.\u003c\/p\u003e\n\u003cp\u003ePhysically, the glass is perfect, with no bubbles. The trim pieces have some scratches as can be seen in the photos, (the main scratches are on the bottom of the trim pieces and can only be seen with the amp upside down)  The top edge and bottom edge of the faceplate trim have some minor blemishes. The rest of the unit has some blemishes here and there, but there are no dents, dings, or deep scratches. Overall it's a very good looking piece. Please see the many pictures in the listing for further details. \u003c\/p\u003e\n\u003cp\u003eThe unit has been fully serviced. All pots and switches were cleaned, and then treated with Deoxit F5 and D5 respectively. We changed all the bulbs in the unit and converted to LED. \u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eWe serviced and updated the driver boards, input board, and meter board. New, caps and heat sinks were installed on the driver board and all caps were replaced on the other boards. We have a bag of the removed parts that can be included upon request. The amp is up to date as far as the last service bulletins that were made on the 2105. The meters were calibrated to factory specifications. \u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eIn order to test the output and check to see the amp was in proper working order, we hooked it up to our Sencore PA81 Stereo Power Amplifier Analyzer acting as a dummy load and Oscilloscope interface. Using an audio generator, we ran a 1k signal through the amps input, slowly increasing the amplitude while monitoring the output on our oscilloscope for signs of noise, clipping, distortion, or improper channel balance. It checked out perfectly, and  the amp easily produced a clean 105 watts per channel on our bench.  Following the work performed on the unit, it spent time on our bench, and then in our house system for about a week running daily for 8 hours a day. It performed flawlessly. \u003c\/p\u003e\n\u003cp\u003eThe MC 2105 will ship fully insured in a new Mcintosh MC 2105 factory box. A signature will be required upon delivery. \u003c\/p\u003e","brand":"Mcintosh","offers":[{"title":"Default Title","offer_id":67731875692649,"sku":"001859","price":2995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0267\/5212\/2985\/files\/B97B533F-2F79-4B9E-997B-A5E973789413_1_105_c.jpg?v=1792854264","url":"https:\/\/recordmarthifi.com\/products\/mcintosh-mc2105","provider":"Record Mart HiFi","version":"1.0","type":"link"}
