The SAE Two P10 at USD $399 is overpriced for the used market. Recent listings show this 100-watt vintage power amp moving in the USD $185–$250 range, suggesting the seller is asking a 60–115% premium over typical asking prices. For a 1980s-era amp with no documented service history, that's ambitious. If the unit is in pristine cosmetic condition with original documentation and has been recently serviced, you might justify the higher end, but USD $399 remains a stretch for this class of gear.
Before committing, verify the amp powers on cleanly and holds stable bias—power supply issues are common in SAE gear of this vintage, and repair costs can quickly exceed the amp's value. Confirm the output transformers aren't buzzing or humming under load, and ask whether the original manual and schematic are included. A working SAE Two P10 with clean internals is solid mid-fi iron, but not at this asking price.
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.
