James Bongiorno, American audio engineer and designer for the past half century, died yesterday at his home in California.
His Dynaco connection: after he assisted in designing several amplifiers at other companies including Marantz (the real company, owned and run by Saul), the first from-scratch, all-Bongiorno design was the Dynaco Stereo 400 power amplifier. He also had a major role in the AF-6 tuner.
After that, Bongiorno went to SAE in Los Angeles, designed the Ampzilla kit amplifier, left to form the Great American Sound Company to produce the Ampzilla and many other pioneering components, and then founded Sumo, which he sold when he was diagnosed with liver cancer in 1984.
The cancer had gone into remission for over twenty years.
