Our most esoteric product is THE 300B PREAMPLlFIER

This is the first and only preamp to feature these classic tubes. We had been designing the 300B into small power amps for many years and have always had great respect for the smooth natural sound of this tube. However, a single 300B provides truly appropriate power and voltage swing for headphones and makes a remarkable line driver. Here is where the impedances are not too low and the power requirements are not too high: ideal for this kind of tube in a single-ended configuration. This was the genesis of a new preamp.

We combine the historic 300B with another classic, the large octal based 6SL7GT, for the input stage- all triodes running in pure Class A operation. To complement this 'retro' feel, we implemented vacuum tube rectification and regulation in the power supply along with plenty of capacity. We also developed an additional (and innovative) ripple rejection circuit to filter out power supply noise making this an incredibly low-noise preamplifier- especially critical for headphone users. Complementing this lovely and rich sounding line-driver is the ALPS audiophile volume control, gold plated RCA connectors, high purity silver wire, mil-spec printed circuit boards with extra thick copper and plating, and custom designed output transformers which we wind right here in our own magnetics department. It all adds up...

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.
