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.

The SX-1250 was introduced in 1976 as Pioneer's top-of-the-line receiver. It reflected Pioneers new styling of matching silver tuning dial with white background signal strength and stereo signal meters. It was Pioneer's most powerful and feature-laden receiver that year, capable of pumping out 160 watts per channel. It was beautifully finished in walnut veneers and solid walnut trim. It had a list price of $900.00 (thats over $3800.00 in today's dollars) and tipped the scales at 65 pounds. The SX-1250's beauty was more than skin-deep. As Pioneer's best receiver, the engineers lavished a major design engineering budget in designing it. There was a careful and logical layout of the receiver's hefty toroidal transformer and four massive capacitors, flanked by the component circuit boards. Pioneer designed large wrap-around heatsinks to dissipate the SX-1250's full-tilt operating temperature. The SX-1250 was the largest receiver Pioneer had ever built up to that time. The engineers needed every square inch they could get to package the components. The receiver measured 22.0 inches wide, 18.75 inches deep, and 7.50 inches high. The quality, power and good looks of this receiver not only made it a popular choice for buyers in 1976 and 1977 when it was offered, it is one of the most sought-after Pioneer receivers today.
