McIntosh MC240 Up for sale is 1 of the most sought after vintage Mcintosh tube units of all time... the MC240 power amp.. The Mcintosh MC240 is in original condition and operates perfectly. There is no hum or tube noise whatsoever when driving a pair of vintage 15 ohm Tannoys. Remarkable. Nothing has been changed, added or removed on the MC240. Tube complement are 4 7027A GE outputs and US made old stock small tubes. No foreign or new stock tubes. All knobs are original and all functions work. The transformers are in mint condition with no scratches. Of the tube amplifiers manufactured in the 60's, the McIntosh line is one of the most coveted and collectable. The MC-240 was one of three stereo amps offered by McIntosh during that time. You will note that the last two digits signified the power rating on a per channel basis. The "2" meant that there are two amplifiers within a single chassis.
Superior craftsmanship The MC-240 was built to impress. One look and you know that you're viewing a piece of Americana. The "Mac" amps look strikingly similar with the large McIntosh logo in front and the sloping left side panel that houses the gain and balance controls, RCA inputs, speaker output strips and power cord. Three massive transformers lie atop the chrome plated metal top plate and brown painted side panels. All the tubes are on top, with the tube sockets attached to the chrome plated top plate. By contrast, what you'll often see today are tube sockets soldered on a circuit board. When one inserts or pulls out the tubes, pressure is directly applied on the circuit board. The MC-240 is rated at 40wpc. The output tubes are 6L6GC. For those unfamiliar with tube amp maintenance, good news--no bias adjustment is required. The unit weighs about 59lbs, mostly apportioned to the rear where the transformers are. It's weight and design provide an overbuilt quality--a component that could possibly outlast its owner. The point to point soldering, parts quality, assembly, and attention to detail are first rate. This is American craftsmanship at its pinnacle.
Music appreciation time Prior to any serious listening, I had the system playing for about two to three hours. Hearing music rendered by the MC-240 is an experience. It has the classic melody of a refined tube amp. One is quickly caught by the spacious soundstage, full-bodied rendition of musical notes, and the thereness quality of the human voice. It makes one wonder why listeners then would opt to replace their tube amps with transistors. The truth of the matter is: (1) speakers and upstream components during that time were not as revealing then as they are now, and (2) most consumers place a higher priority on convenience.
