NIB/NOS 2026 Literally new - DEAD MINT. 4 channels of glorious Neve 1073 Mic Pres w/Cinemag Transformers. Fully tested. Purchased for a client's gear rider and the client was a no-show. Their loss is your gain. Feel free to ask any questions. Local Pick Up preferred at Third Coast Guitars Palatine, IL but will ship for actual cost. Here's more info from Lack Lion Audio:

Black Lion Audio B173 Quad Preamplifier
Please give a warm welcome to all 70dB of Black Lion Audio's latest iteration of 1073-style gain, the B173 Quad! Rather than "just another clone," the B173 Quad seamlessly combines vintage character with modern sensibilities in a stylish 2U chassis with a feature set to satisfy the most demanding of audio engineers. A revamped gain stage and lower noise floor pave the way to a cleaner, lower distortion sound, while Cinemag input and output transformers keep things smooth and warm. Two front panel D.I.'s impart a harmonically rich tone to guitars, keyboards, and synthesizers, and stepped input gain and variable output attenuation allow for perfect control over transformer saturation. Metering on all 4 channels displays how hot your output signal is hitting the parallel TRS/XLR outputs, and an external power supply keeps noise out of your tracks!

At $250/channel, there's no reason not to add a B173 Quad to your front end arsenal!
