Pioneer SX-636 Stereo Receiver from 1974. In Excellent condition, please check the photographs. Serviced to include cleaning inside and out, all the pots and switches have been treated with switch cleaner, known issue noisy transistors replaced in the pre-amp, and the bias currents and offset voltages have been set. Soak tested for the last few months and 100% working, sounds lovely. This is a beautiful classic HiFi unit that would great in a modern environment. Original box included. Local collection or delivery via DPD courier, will be well packed. I have some other vintage HiFi Receivers for sale, please check my feedback and other listings. Thanks for looking. From HiFi Engine: DescriptionNot all high fidelity situations require high powered equipment.If your listening room is of average size, and what you really want is more efficiency and more sophisticated versatility in a medium-powered model, Pioneers new SX-636 will be a good choice.It incorporates the latest state-of-the-art advantages for superior high fidelity performance. But it saves you money and doesnt waste watts.The FM tuner employs a low-noise FET and a frequency-linear 3-gang variable capacitor in the front end. The FM IF section features a 5-stage limiter of high-performance IC and phase-linear ceramic filters. And to ensure stability under all operating conditions, the FM MPX circuit is the advanced PLL (Phase-Lock-Loop) type with an IC.FM results are impressive: 1.9pV (IHF) sensitivity, capture ratio of 1.0dB (IHF), 60dB selectivity (IHF), signal-to-noise ratio of 70dB and wide separation of more than 30dB over the 50 to 10,000Hz range.Accurate high fidelity reproduction is achieved with a particularly precise phono equalizer in the Pioneer SX-636. It keeps RIAA deviation within +- 0.5dB.And as for power, the advanced direct-coupled OCL power amplifier provides continuous power output of 25 watts per channel, min RMSat 8 ohms from 20 Hertz to 20,000 Hertz with no more than 0.5% total harmonic distortion.This is enough to drive up to two pairs of stereo speaker systems independently or simultaneously with brilliant, high fidelity results.As a stereo control center the SX-636 is up to the minute - there are two stereo pairs of tape terminals (deck 1 to deck 2 tape duplication is possible), a function switch to handle FM, AM PHONO, MIC and AUX. An FM-linear dial scale with dual meter tuning system, illuminated program indicators, a stereo headphone jack and other conveniences add to the versatility.The efficient Pioneer SX-636 puts stereo power in its place - with no wasted watts or wasted money for your stereo pleasure.SpecificationsTuning range: FM, MWPower output: 25 watts per channel into 8?
