Description When you go to buy a new receiver, ask yourself these questions: Does its FM tuner section guarantee high performance of spurious rejection as well as high sensitivity? Does it include the very latest electronics circuit technology to assure a constant stable and high quality sound reproduction from small to large power output? Are you going to be proud to own it for a long, long time? Pioneer's new and elegantly designed SX-1250 AM/FM receiver provides a resounding yes to each of these questions - and then some. No other Pioneer receiver provides such incomparable FM performance and sensitivity and then combines it with mammoth continuous power output of 160W per channel, min RMS at 8 Ohms, from 20 Hertz to 20,000 Hertz, with no more than 0.1% total harmonic distortion. Specifications Tuning range: FM, MW Power output: 160 watts per channel into 8Ω (stereo) Frequency response: 10Hz to 50kHz Total harmonic distortion: 0.1% Damping factor: 30 Input sensitivity: 6.5mV (mic), 2.5mV (MM), 150mV (DIN), 150mV (line) Signal to noise ratio: 75dB (MM), 90dB (line) Output: 150mV (line), 30mV (DIN), 1V (Pre out) Speaker load impedance: 4Ω (minimum) Dimensions: 556 x 186.5 x 464.5mm Weight: 29.2kg Year: 1976 Downloads.

60 plus pounds of pure pain with the power to crush and contain! Vinyl never sounded better after adding this massive beautiful receiver. Power weight and warmth with exceptional detail packaged in a beautiful chassis that exudes fine design. At night this receiver adds to and never distracts from the living environment.

As you can see I love it and will never part with it. Reviewed Dec 19th, 2017 by I am the proud owner of a SX-1250, I always thought they were the epitomy of 70's technology, for the most part all the heavy hitters of that era were in the wattage wars till after 77-78. After then they started to scrimp on the quality of the units, even though they might have produced more wattage, build quality suffered some. The 1250 was probably the best quality, easiest to repair, receiver ever made. I just did a 100% redo on mine less resistors, and a few diodes. I suspect this unit will last another 40 years, long after I'm gone! Beautiful, Powerful, Reliable, and a sound that only the high end receivers can deliver.

If you have the opportunity to get one, pull the trigger, have it redone and revel in the warm tubelike sound for the rest of your life. Enjoy the music!! Reviewed Mar 01st, 2015 by My dream came true! I was already a proud owner of the Pioneer SX-850, now a SX-1250 just fell into my hands. It's near mint except the wood which has it's normal wear.

It has already been recapped just needed another cleaning which I have spent all weekend cleaning every piece of it with great care. I have the speakers to support this and I have a QA-800 Quad amp coming next week. I listened to it before I bought it. It's the bomb! If you have a chance to buy on of these I highly recommend it as they are soooo choice!;-) Happy Dayz. Hello, I did not put the pencil makes in, but have worked on many Pioneer power supplies. I would concentrate on the +25v section as this seems to provide a reference for the 13.5V and 5.4v supplies as well.
