TUBE-TECH has been around for 40 years, and over the years, more than 15,000 Blue Units have been shipped from Lydkraft, Denmark. Lydkraft was founded in Denmark in 1977 by John G.Petersen and two partners. The company originally served the PA market but turned away from this area of business in 1980 when John Petersen took over the company and focused his efforts towards the design, development and manufacturing of direct boxes, mixing desks and speaker systems.
Due to decreasing sound quality from modern studio consoles, the demand for vintage high quality tube gear was increasing and John decided to start development of his own units in 1984. John’s fascination of classic high-quality analog sound made him start designing the TUBE-TECH line of all-tube signal processing equipment. Production of the first TUBE-TECH unit took place in Johns private garage, and the PE1A Program EQ and Midrange EQ ME1A were almost direct copies of the Pultec units, since John wanted this high quality design to be available to a bigger group of studio customers. After these two units followed the whole line line of “classic” TUBE-TECH units, all designed from the ground up by John G. Petersen.
