For sale is a nice SAE 2400L rack mountable solid state stereo power amplifier. Unit is in good working order and built like a tank.
The SAE 2400L has a strong reputation as a classic, high-current stereo power amplifier, and USD 599 is an ambitious ask here: it sits above the recent comparable 75th-percentile price of USD 499 and well above the USD 400 median. It is not automatically unreasonable for an exceptional, fully serviced example, but an unknown-condition unit should not command that premium.
Its appeal is straightforward: substantial power, a robust vintage build, and the kind of authoritative drive that suits demanding speakers. At this price, insist on a convincing demonstration of both channels, quiet operation, healthy meters and controls, and evidence of competent service—especially given the amplifier’s age. Unless it is unusually clean or recently restored, negotiating toward roughly USD 400–USD 500 would make this a much more compelling buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# SAE (Scientific Audio Electronics)
Scientific Audio Electronics emerged from Los Angeles in 1968 when Morris Kessler partnered with Ted Winchester and Beth Winchester to pursue an ambitious goal: building the world's finest audio amplifier. Kessler had been designing and hand-building amplifiers since the early 1960s, and the partnership formalized his vision into a commercial enterprise. The company operated through the 1980s, establishing itself as a significant player in the golden age of solid-state hi-fi before ceasing operations in 1988.
SAE built its reputation almost exclusively on power amplifiers, introducing the Mark 2—a 60-watt solid-state design that earned comparison to the legendary Marantz Model 9 tube amplifier in Stereophile magazine. Beyond amplifiers, the company pioneered several audio innovations, including the world's first graphic equalizer, the first digital read-out tuner, and the first phonograph pop-and-click filter. These products reflected SAE's engineering-forward philosophy and commitment to advancing high-fidelity technology.
SAE occupies a revered position in vintage hi-fi collecting and audio history. During the 1970s, the company was synonymous with high-end solid-state amplification, competing directly with established names like McIntosh, Marantz, Pioneer, and Sansui. Their equipment commanded premium pricing—a complete SAE rack system retailed for $6,000, equivalent to a top-tier Cadillac. Today, SAE remains a collector's brand, remembered by audiophiles as a legitimate innovator that produced musically open and refined components during hi-fi's most formative era.
