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. The ARC 76A is a favorite among vintage audio collectors and tube rollers. This one is in what we call “survivor” condition, original and unmolested. We fitted a new set of tubes and did a light service to get it working nicely. Cosmetic condition is good with only a few visible signs of use, please look over our photos for more info. SkyFi Service Notes: This unit appeared to be all original on initial inspection. After testing all of the tubes it became clear that the output tubes needed replacement. We swapped out all of the 6550′s and biased them up to service manual spec. The input attenuators and jacks were also cleaned. After service, this amplifier tested clean above up to its rated 75W with ease. SkyFi Cosmetic Notes. The terminal strips exhibit the typical cracked barrier guards that we normally see on units of this age. Using period correct small spade connectors or spade to banana adapters is encouraged. Light marking under left handle of face plate. Light black paint marks on face plate. All 6CG7s are vintage GE, all testing well on our Modern and Professional Amplitrex AT1000 Tube Tester. 12AX7′s are a mix of GE and RCA, also tested well on our Amplitrex. The original GE 6550′s were at the end of their lifespan and were replaced with two matched sets of known good Svetlana Gold Label 6550 from our stock. All tubes biased to service manual spec. The 6550 in the power supply section was also replaced with a Svetlana tube. More from Audio Research. POWER OUTPUT 75 Watts per channel minimum RMS (both channels operating) into a 4, 8 or 16 ohm load from 20 Hz to 15 kHz with less than 1% total harmonic distortion. 1.5 volts for rated output. 80K ohms at 20 Hz; 30K ohms at 15 kHz. 4, 8, 16 ohms. 14 at 8 ohms (1 kHz). Intermodulation distortion: less than. 5% at rated power. More than 80 dB below rated output. 100, 120, 200, 220, 240 VAC; 50-60 Hz, 550 watts at rated power output. (4)12AX7, (8) 6FQ7, (2 matched pairs) 6550, (1) 6550. 19″ W x 7″ H x 12-1/4 D. The SkyFi Testing Process for Tube Amplifiers: We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and tubes are inspected for signs of stress overheating or cracking. We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If it all looks clean we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier the remains powered on to “burn in” on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will also be tested. We also test all tubes for output gain and leakage on our calibrated B&K 747 tester against the original manufacturers specifications. If needed, the tubes will be replaced from our vast NOS (New Old Stock) vintage or modern inventory. Final testing involves pushing actual music thorough the amplifier. We’ve learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we’re very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice. We have too many items for sale and it’s nearly impossible to keep track of offers outside of the official system. We accept trade-ins of equal or lesser value under certain conditions. Please visit our website to submit your gear for full consideration. We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. And will typically pass on displays, projectors, receivers, dated surround processors, and mid-fi equipment of any type. We will offer a fair value for your equipment, but keep in mind we’re running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment. SELL US YOUR GEAR (Working or Broken). Simply visit our website to submit your gear for full consideration. We are currently operating from our shop inside our dedicated building in Glen Rock, NJ. We have several well-equipped and dedicated listening areas, plus a dedicated listening studio with tons of equipment of all makes and models. We’re not a store, so please don’t make an appointment if you’re just curious as to how a speaker or piece of equipment sounds. In essence – no tire kickers please. This is super useful when purchasing large speakers or heavy amplifiers. It’s also great for ensuring your new turntable is setup correctly in its final resting place.

ONE VINTAGE 1928 TUBE POWER AMPLIFIER from WESTERN ELECTRIC ERA, for use with one single ended 250 output tube and one 280 rectifier tube, tubes are NOT with this listing, i like my 250 tubes and not parting with them yet. The power transformer tests good, and the input transformer also tests good, no other testing was done. Please note this amplifier never had an output transformer, it was originally connected to a high impedance speaker, and will need some work to use it. Also in another listing i have other pre-amps designed to go with this amp chassis.
