Manley’s first commercially available products were upper echelon high-fidelity vacuum tube amplifiers and preamplifiers constructed at the old Vacuum Tube Logic of America factory.
On January 30, 1989, a 20 year old EveAnna on sabbatical from her studies at Columbia University met the crew and was hired on to the production team. She quickly learned to solder and assemble vacuum tube amplifiers, and after training a new team of assemblers, EveAnna worked her way into the Quality Control department.

It was at this time that the first Manley professional products were developed, starting with the original 1u Reference 60dB Microphone Preamplifier and soon followed by the Manley Enhanced Pultec and Mid Frequency Equalizers. These products, along with the Manley Reference Cardioid and Reference Gold microphones, all made their debut at the 1990 Los Angeles AES Show.

In 1993, Manley Laboratories, Inc. became a separate entity apart from VTL.
The new Manley Labs factory at 13880 Magnolia Ave. in beautiful and bovine Chino, California was outfitted to house the Manley Hi-Fi and Pro Studio manufacturing as well as the Langevin production lines, our newly acquired machine shop, and printed circuit board facilities. The following year, the factory’s capabilities were augmented by the addition of a computer-controlled mechanical engraving machine and, very importantly, a transformer winding department
