About this listing
The Pioneer SX-850 is one of the standout receivers from Pioneer’s classic 1970s SX series, combining substantial build quality, a beautiful silver face, analog tuning meters, warm dial illumination, and a real wood cabinet.This example has been professionally serviced and extensively recapped by 617HiFi in Brookline, Massachusetts.The work went well beyond a basic cleaning or “checked out” service and included extensive capacitor replacement, amplifier adjustment, control servicing, and repair of a damaged tape-monitor switch.It is a strong choice for someone looking for a classic SX-850 that has already received meaningful professional attention while retaining original components where they continued to test properly.🔧 Professional Service / Extensive RecapProfessional service included:Extensively recapped across the serviced electronic sectionsMain filter capacitors retained because they tested goodTwo power-supply capacitors retained because they tested goodAM/FM tuner board remains originalDC offset checked and setAmplifier bias checked and adjustedPotentiometers and switches cleaned and lubricatedPreviously broken tape-monitor switch disassembled and professionally rebuiltReceiver tested following serviceI intentionally describe this receiver as “extensively recapped” rather than “fully recapped.” The main filter capacitors, two power-supply capacitors, and AM/FM board were retained rather than replaced.I prefer to disclose exactly what was—and was not—replaced rather than overstate the restoration.Internal photographs documenting the work are included in the listing.✨ Detailed CleaningAs part of the preparation process:Control knobs were removedKnobs were ultrasonically cleanedThey were then hand-cleaned and finished before reinstallationExterior surfaces and controls were carefully cleaned as part of the final preparationUltrasonic cleaning helps remove decades of accumulated residue from the detailed surfaces and grooves that are difficult to clean effectively by hand alone.🎛️ Cosmetic ConditionThis SX-850 is in very good vintage condition overall and presents very well for a receiver approaching 50 years old.The brushed-aluminum faceplate is clean with strong lettering. The knobs, switches, tuning dial, meters, and controls present nicely, and the wood cabinet gives the receiver the classic Pioneer appearance these units are known for.There are normal signs of age and prior use consistent with a vintage component of this era.Please examine all photographs carefully, as the photos are part of the condition description.This receiver is not represented as collector-mint or cosmetically perfect.🎵 Why the Pioneer SX-850?The SX-850 occupies a particularly desirable position in Pioneer’s classic receiver lineup.With approximately 65 watts per channel, it delivers substantial real-world power while avoiding the enormous size and weight of some of Pioneer’s larger flagship receivers.Features include:65 watts per channel into 8ΩDual phono inputsAUX inputDual tape facilitiesTape monitor functionsPre-out / power-in connectionsA/B speaker outputsBass and treble controlsTone turnover controlsHigh and low filtersLoudness controlFM mutingAnalog signal-strength and tuning metersLarge weighted tuning controlClassic Pioneer illuminated dialReal wood cabinetIt works equally well as a daily listening receiver or as the centerpiece of a vintage audio system.🛠️ Bash Vintage AudioI specialize in carefully selected vintage audio equipment with an emphasis on:Professional servicingAccurate condition descriptionsTransparent service historyCareful testingDetailed cleaningSecure packing and shippingI do not use terms such as “fully restored” or “fully recapped” unless the documented work actually supports those descriptions.With vintage audio, transparency matters.
