SkyFi Audio - Curators of Vintage Audio GearSkyFi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of high end audio equipment. We only buy equipment that we admire and are passionate about. 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. If it does not meet or exceed the original manufactures specifications, it will not be sold. We are very selective about the equipment we purchase, focusing on mostly analog, high-build quality, American, and European built units.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.----------One of the coolest Preamp-Tuners made in the 1970's. Plus it's featured on The Vintage Knob website so you know it's something very special... Utilizes Nixie tubes for the FM tuner frequency display which is super neat. Also has a unique preset design which is very clever and well engineered. Construction quality is top notch which is what we've come to expect from ReVox. We performed a light service on this unit, checked and cleaned all controls, and confirmed that everything works as it should. Plus is has the ability to work at just about every input voltage which we also tested. SkyFi Service Notes:• Tuner works beautifully • Removed all covers and cleaned faders and switches More from The Vintage Knob:Rare ultra-high-tech digital "preceiver" (preamp + tuner) holding everything that was the future in 1973. Beautiful beast, too.Most fascinating are five radio stations presets: Fiddle with the left pots, memorize with the buttons to the right.Quartz tuning, 6-gang varicap, FET-charged amps, 8 passive filters, 23ns delay demodulator, PLL 76Khz oscillator for the MPX section.And four beautiflly glowing tubes for display.The preamp section also has just about everything: Adjustable inputs (within 20dB), lo/hi filters, loudness switch, bass /presence /treble tone controls, "null" balance for headphones listening, tape dubbing and monitoring, two preamp outputs with "power-on" triggers, two headphones' outputs and a wired remote for balance, loudness and volume.Fot the ultimate in mid 70's frills, the A720 could be hooked to the high power and fan-cooled A722 mid-size power amp and the A724 Quadriphonic SQ / RM / QS 4-channel decoder / power amp - now you understand why the balance can be remote-controlled on the A720 :)The power-on triggers of the A720 work with an optocoupler + triac and can automatically power-on several power amps and (active) loudspeakers. More from ReVox:In the Revox A720 the advanced circuit technology of a digital FM tuner is combined with an audio preamplifier section of outstanding characteristics.By not incorporating a power amplifier section, extreme flexibility with regard to its combination with external equipment could be achieved.In this digital FM tuner preamplifier, complex and unusual circuit solutions have been realized through a high degree of integration, thereby ensuring exceptional operational reliability.Outstanding frequency stability in station selection is achieved through crystal referenced synchronization of the local oscillator.To ensure this high quality and accuracy in performance, each unit has to pass through a series of tightly controlled production tests plus a careful final inspection step.
