About the Designer...
Superpower was designed by an Electrical Engineer with circuit design experience dating to 1971, when he designed his first reverb unit with a ceramic phono cartridge, 4 ball point pen springs, a model car hub cap, a small transistor amplifier and a speaker.
He was author of a somewhat controversial article in issue 1 of Glass Audio called "A Self-Bias Servo for Push Pull Amps", and has designed circuits as varied as a cascode tube preamp, an 18 bit D/A converter, a 16 bit A/D converter, a diamond tester, a caller ID adapter, a high speed (for the time) CMOS digital character generator, op amps, voltage regulators and more. He also spent a portion of the 1980s designing test equipment for op amps, data converters, micromachined sensors and other analog and mixed signal devices.
In the early 1990s he started and sold a commercial software company, started a company making caller ID systems and software components. Later that decade he wrote a book The Fundamentals of Mixed Signal Testing which covers analog and DSP techniques for measuring and testing analog and mixed signal devices, and its accompanying training software.
He holds U.S. patent 8,294,440 on the Superpower design.
