General information [contribute]

Kerry Gray (August 2000): SAE made a speaker in the 70's that I refered to as the ski slope speakers that was sold though pacific stereo at one time. I am sure they used the RTR stat Mids & tweeters. Were these the Mark X1V's costing $2000 ? Can anyone provide information on speakers made for SAE that were Electrostatics.

Don McRitchie (August 2000): I still own a pair that I bought in 1976 for around $2000US. I'm currently using them as rear speakers and have attached a picture of them in my home. I'm not sure who made the panels. I was under the impression they were made by Janzen. The 12" woofer is made by Gauss, a company primarily known for sound reinforcement speakers. That driver has one of the largest magnet structures I've ever seen. SAE made another electrostatic hybrid called the Mark XII. It was a large, floor-standing, rectangular box but I'm not sure of the driver complement since I never saw one. Regards, Don McRitchie Webmaster James B Lansing Heritage Website


Ali Spot (November 25, 2009): In and around 1967, this is where it all started. Ted Winchester had the idea to further develop an audio amplifier designed by his friend, Morris Kessler. It was a simple idea to build the world's best audio amplifier. No small task but oh what a challenge. Ted had first met Morris while perusing a local audio shop, Hi Fi Corner. Morris was designing, building and selling some of his home made amps while working now at Sound Center.

Their bench mark was the Marantz Nine, "The" amplifier of the day. So, Ted bought an HP analyzer, an HP 200-CD oscillator [low distortion version] and a Crown IM analyzer. They were ready and set off to design and build the "world's best" audio amplifier. To achieve this, the amp had to pass Ted's "screw driver death test" ( any frequency 20Hz to 20KHz, sine wave driven amp to full power, then short the output terminals with a screw driver). Needless to say this produced a lot of dead 2N3055's, but it also produced the fruit of their labor, the Mark Two.

Scientific Audio Electronics (SAE) was officially commenced in 1968 with a Partnership Agreement between Ted Winchester, Morris Kessler and Beth Winchester. They needed a logo, so Ted took out some Bishop Graphics PC board drafting tape and designed the stylized "S" and "E" symmetrical with the "A", SAE was born. The Mark Two was no beauty, but it didn't have the "transistor sound" like other amplifiers of the day. Still it was difficult to sell an "orphan" power amp to the audio emporiums of the day. Their customers wanted the Marantz and Macintosh full-line with front panels/rack cases look. That changed with a review in Stereophile. Gordon Holt was reluctant at first to review the "orphan" amplifier that was not available nationally. On the telephone, in effect he said, "Well you (Ted) have made me curious and either you and your friends all have tin ears if you and they think it's the solid-state equivalent of the Marantz Nine or you've made the only solid-state amp worth buying. Gordon's most generous praise of the Mark Two in Stereophile most likely started the SAE legend.

In the early 70's, Ted was designing and manufacturing graphic equalizers separately under Linear Transducer Designs (LTD) that SAE marketed through the mid 70's. All LTD manufactured SAE equalizers and SAE preamp-equalizers are identifiable by the "Copyright LTD 19XX" on every circuit board except the Mark 1B.

Along the way, Morris was joined by the likes of the great Ed Miller and James Bongiorno, to name just a couple. Morris sold SAE, Inc. in 1988 to a company that in turn sold it to DAC. They were trying to reach the masses and had the SAE TWO line built overseas. It was the beginning of the end for the SAE banner.

James Bongiorno started GAS (Great American Sound) which also built some classic amps, like the Ampzilla & Grandson. Bongiorno sold GAS and started a third company, Sumo, and designed still more classic amps, and a tuner called Charlie the Tuner. Then in June of 1994 Morris Kessler and Mike Pontelle joined under the banner of Amplifier Technologies, Inc. ( ATI ) .

For almost two decades, SAE made some of the best known home audio amplifiers. In the early Seventies, if one wanted the best in solid-state amplification, SAE came to mind. Known then internationally as purveyors of open and musical products, SAE lingers in the minds of audiophiles old enough to remember as a company that really produced. These amps were so popular, they took Japan by storm way before single-ended tube amps became retro-cool in the land of the rising Sun.
