LaChapell Audio Model 583s Original 2-space 500 Series version, open box Close-Out SALE

The LaChapell Audio Model 583s is the world’s first vacuum tube preamplifier designed for the 500 series format. Based on our popular 992EG, the 583s is a must-have preamp for those looking to add that extra warmth and character to their “lunch box” collection found only within the thermionic realm. Our initial design approach was simple; identify and extract the key design elements of the 992EG that directly contributes to its’ sound signature, and then inject that into the 583s. This, of course, is the amplifier’s input stage, where the lion share of your signal’s quality and character is generated. While the 583s utilizes a more traditional single-ended amplifier configuration, the overall topology of the 583s’ microphone input stage is equal to that of the 992EG; specifically, feedback loop configuration, input transformer turns ratio, input impedance, capacitance, etc. Together with the CineMag CMOQ nickel alloy output transformer, the 583s also features an ultra clean output stage using premium Burr-Brown & THAT Corporation balanced line drivers. 

The 583s is built to be a good neighbor to your other 500 series modules. With the exception of the tube access opening, the 583s has an enclosed chassis, which helps direct cooling and prevents any unwanted interference. In operation, the user has individual control over the input and output gain stages via fully variable potentiometers. Lke the 992, it provides total flexibility to explore the 583s’ broad sonic pallet, enhancing its versatility.

Additional functions include four illuminated NKK toggle switches for 48v (Phantom), db input pad, polarity reverse and input select.
