No mid-fi, no gimmicks, no junk. Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. This vintage pair of McIntosh MC60 monoblock amplifiers were modified by a hobbyist at some point in the past. One amp has a choke in the power supply, the other does not. The amp without the choke also has some neon bulbs on the tag board as shown in our listing photos. The slight differences in design do not affect the final outcome, as they tested the same in our lab and in our listening tests. Both amps were tested at our bench and fundamentally work. Both were driven into clipping with a 1 kHz sine wave and meet the official McIntosh 60W power specification. Although these amps technically work, we recommend further service/restoration before putting them into daily use. They are both good bones for a restoration, or someone looking to experience the glory of vintage tube monoblocks from McIntosh. During our testing we did notice an intermittent issue where the grid bias of one output tube would drop, causing the associated tube to red plate (not what you want to happen with any tube in operation). This issue was resolved by swapping out the final 12AX7 tube before the output tubes. Please note this listing includes the 2 x MC60 units, along with the vacuum tubes pictured in our images.

McIntosh MI-75 – 75 Watt Mono Power Tube Amplifier – Rare & Vintage. Up for sale is this McIntosh MI-75 power amplifier. This power amplifier comes from a professional studio and is fully working. Though not pictured, this power amp does have a faceplate but does not have the controls or logo badges as seen on similar models. This amp was homed on top of a rack shelf so the controls were installed on the side of the unit. For more than six decades McIntosh has maintained dominance in the high-end audio industry. McIntosh’s permanence in the marketplace is owed to its history of phenomenal components, all adhering to the same design criterion set forth by Frank McIntosh and Gordon Gow; superior sonic performance and unmatched reliability. Every component was created with capacity so great that it will never be operated at or near its stress point. A good reason why an estimated 80% of the McIntosh components produced since 1949 are still in use today and what’s more amazing is these same components are outperforming modern counterparts with the benefit of years of technological progression. The item pictured is the one you will be receiving. No additional accessories included. All merchandise has been tested. Any issues found are noted clearly in the description above. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps”. The seller is “chulino” and is located in this country: US.
