Amazing Tube Pre for Your 500 Series Rack!

Based on the legendary 992EG, the LaChapell Audio Model 583s is the world's first 500 series-format vacuum tube microphone preamplifier. This preamp uses a traditional single-end configuration, starting with a Jensen JT-115k input transformer, Burr-Brown & THAT balanced line drivers, and a CineMag CMOQ nickel alloy output transformer - an overall topology similar to the 992EG. Another great thing about the Model 583s is that you get easy access to its 12AX7 vacuum tube, so you can experiment with different vintage tubes. The result is not only a microphone preamp that has a timelessly deep quality, but one you can customize to taste. If you're looking for a way to add extra warmth and amazing character to your 500 series rack, you won't find anything else quite like the Model 583s.
