COPENHAGEN, DENMARK – NOVEMBER 2010: For twenty-five years, engineers and producers the world over have associated the no-nonsense blue faceplate and white typeface of TUBE-TECH analog processors with the lush, dimensional sound they impart to any audio that flows through them. After 25 years in business, TUBE-TECH president John G. Petersen continues to craft their equipment with simple, elegant circuitry using only premium-grade components. From the start, Petersen designed TUBE-TECH gear using only vacuum tubes in the active signal path and only transformers on the inputs and outputs. Since the first the design of the first Program Equalizer PE 1A in 1985, over 15,000 TUBE-TECH units have shipped from the headquarters of parent company Lydkraft in Denmark. Because their lifetimes are measured in decades, almost every one of those units is still helping make the music of today sound much better than it would have otherwise.
Before TUBE-TECH became a reality, Petersen had received a degree in electrical engineering from Danish Post and Telegraph and took a job in 1972 at the Danish Broadcasting Company (DBC). In his role as maintenance engineer, he received factory training at Solid State Logic, EMT, Studer, Sony, Neumann, NTP, and Lyrec. His genius for inspecting, understanding, and repairing audio circuits paved the way for TUBE-TECH. “A friend of mine was opening MOX Studio in Copenhagen in the mid-1980s,” said Petersen. “I helped him refurbish all of the gear that was going into it, including two Pultec equalizers. I was skeptical about those boxes. They looked like they belonged in the city dump! But they tested nicely and, more importantly, they sounded amazing.” more
