Mercury Recording Equipment M72s Stereo Tube Preamplifier

Up for sale is a world-class Mercury Recording Equipment M72s tube studio microphone preamplifier in excellent condition. Purchased brand new and recently decommissioned from active service in a pro studio, this flagship 2U rack unit delivers the definitive "REDD.37 console push." It is a meticulous, all-discrete modern recreation of the legendary Telefunken/Siemens V72s valve modules used by George Martin and The Beatles at Abbey Road Studios. [1, 2]

• Studio History: Used with immaculate care in a smoke-free, climate-controlled professional control room environment.
• Abbey Road Pedigree: Modeled after the ultra-rare "V72s" variant (not the common V72), providing a massive, three-dimensional mid-forward presence and a velvety analog low end. [1, 2]
• Modern Features & Control: Upgraded from the fixed-gain vintage modules to offer a variable 28dB to 58dB gain range stepped in precise 3dB increments. Includes onboard 48V phantom power, phase reversal, and selectable -16dB or -28dB input pads.
• Line-Level Mojo: Engaging the -28dB pad at its lowest setting lets you run full stereo mixes, individual instrument stems, or virtual instruments through its massive custom transformers and tube paths to add instant analog glue.
• Proprietary FDI Circuit: Features front-panel JFET Direct Inputs based on a Class-A tube topology. The DI signal paths feed directly through the core preamp circuitry and input transformers, adding unparalleled thickness to bass and electric guitars.
• Functional State: 100% operational across both channels. Switches, heavy-duty Bakelite knobs, and internal valves track perfectly without noise, crackle, or signal dropouts.
• Cosmetic Condition: Excellent aesthetic shape. The gorgeous, vintage-accurate powder-coated faceplate is pristine and fully legible, with only the lightest standard signs of rack placement on the chassis edges.
