Mark Levinson No. 380S Dual Mono Preamp - Factory Serviced Mark Levinson No. 380S Dual Mono Preamp - Factory Serviced General: The 7270 is by FAR one of our favorite vintage amps from McIntosh and by far one of our most popular sellers. They are easy to service, super reliable and built to last a century. Aesthetically it meets all the requirements - large chassis, big blue meters, glass & metal faceplate, and BIG power. This particular sample is in great shape and passed all of our internal tests with ease. SkyFi Cosmetic Notes: • Perfect Glass Faceplate. • Light blemishes on top metal surfaces and sides. • Lighting is original incandescent. *Entire faceplate is a condition 8-9 and so is the top, but the sides do have a few scratches bringing overall condition to 7. SkyFi Service Notes: • Glass Replaced w/McIntosh Factory Official Replacement. • Controls Cleaned. • DC Offset and Bias Adjusted to Service Manual Specification. • Meter Watt / Hold Switch Replaced. • Meters Calibrated. Brand Background: McIntosh Laboratory is an American manufacturer of handcrafted high-end audio equipment based in Binghamton, New York. The company was founded in 1949 by Frank McIntosh. The company designs and produces audio amplifiers, stereo tuners and other consumer electronics products. Ownership: Single Owner Connections: RCA inputs, Screw Terminals for Speakers, Captive Power Cord General Sound: Big beautiful musical sound with little fatigue. Cosmetic Condition: 7/10 = Good. One or two minor scratches. Well Maintained. See our detailed rating description here. Working Condition: Working perfectly and tested in our lab and listening room. Included: Just the unit and power cord. Packing: Original Manufacturers Packing Specs: PERFORMANCE GUARANTEE Performance Limits are the maximum deviation from perfection permitted for a Mclntosh instrument. We promise you that when you purchase a new MC 7270 from a Mclntosh franchised dealer, it will be capable of or can be made capable of performance at or exceeding these limits or you can return the unit and get your money back. Mclntosh is the only manufacturer that makes this statement. PERFORMANCE Mclntosh audio power ratings are in accordance with the Federal Trade Commission Regulation of November 4, 1974 concerning power output claims for amplifiers uséd in home entertainment products.

Dimensions: 16 3/16 inches wide (41.1 cm) by 7 1/8 inches high (18.1 cm) by 14 1/2 inches deep (36.8 cm), including connectors. Knob clearance required is 1 1/4 inches (3.2 cm) in front of mounting panel. Weight: 82 lbs. Testing Process: We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. If the amplifier passes visual inspection, we move on to a controlled power on sequence using a Sencore safety analyzer to monitor current draw in real time. Once the amplifier is determined to be safe to operate, we connect it to full AC mains for function and power testing. We connect the speaker outputs of the amplifier to a Sencore PA81 Power Analyzer which acts as a dummy load, DC offset monitor, and oscilloscope interface. We start with a low level 1KHz test signal at the amplifier’s input and slowly increase its amplitude while monitoring the output on an oscilloscope for signs of noise, clipping, distortion, or improper channel balance. We continue increasing the signal level until the amplifier reaches clipping. At this point we take an output power measurement and compare it to the spec sheet of the amplifier to verify proper performance. If the device under test has both balanced and single ended inputs they are both tested at this time. We finish off the bench evaluation with a 1KHz square wave check and a 20Hz to 20KHz sine sweep to assess the amplifier’s frequency response characteristics. This battery of tests will usually reveal if the amplifier has any issues that need further attention. Before the device leaves the bench, we perform a listening test with actual music using a variety of preferred test tracks. Our benches are outfitted with familiar monitor speakers which help us identify inconsistencies that will not always show up on our test gear. The main things that we are listening for are hum or noise with no signal present, proper center image, clicks, pops, or any other obvious undesirable audio characteristics. If the unit passes all of these tests it is moved to our long term testing rig where we simulate real word operating conditions for 6-8 hours. This allows us to monitor the unit for signs of thermal runaway or intermittent issues that only crop up when the unit has fully come up to temperature. *Scroll down to view additional images for this listing and click to enlarge. **Please note we are not a repair shop and only restore what we own. ---------- SkyFi Audio - Curators of Vintage Audio Gear SkyFi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of high end audio equipment.
