Manley Laboratories Inc

About Manufacturer

The MANLEY brand has been around since the late 1980's. 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.

In this history lesson, we'd like to direct special focus on our people at Manley Labs. The people whose years of dedication, service, and expertise bring you people, our customers, these products. It's all about the people...

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. Baltazar Hernandez, already with two years experience, taught her how to solder in those first few days. It was in 1989 that the first Manley professional products were developed, starting with the original 1u Reference 60dB Microphone Preamplifier and soon followed by our Manley Enhanced Pultec and Mid Frequency Equalizers. Baltazar and EveAnna, busy building gear, were soon joined by Saulo and Ramiro. Just next door, Elias was employed by a printed circuit board maker later brought into the Manley Labs fold when 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 HiFi and Pro Studio manufacturing as well as the Langevin production lines, our newly acquired machine shop, and printed circuit board facilities.
