Got vintage preamp or outboard modules needing a new home? Placing this circuitry in a new rack unit provides an opportunity to refresh the look and improve functionality. 

For this project, our friend Ken supplied us with a pair of vintage Neve 33415 Line Amplifiers, which originated from a 8068/8078 era Neve console. He acquired them racked in a 1U chassis with a stand alone power supply. The original design did not include any signal or phantom power presence LEDs and rudimentary function labels taped on the front panel. 

We took the 2 modules out of the original unit and housed them in a brand new chassis of our own. We added our own power supply board, a signal presence and clipping indicator LED, phantom power presence LED, and replaced the pots and switches. The end result was a convenient, self contained 1U 2 channel mic preamp with integrated linear power supply. This project also called for a new faceplate, as the previous build had the modules protrude out of the front face of the chassis. We custom designed and fabricated a faceplate with helpful function labels for a sleek look. 

We build power supplies for all formats and specifications! 

Pictured is a standalone 500 Series Power Supply Unit (PSU) built for our friend Jonathan, for use with his DIY 500 Series chassis. It uses a toroidal power transformer and integrated circuitry on a board to generate +/-16 Volt rails and a +48 Volt supply, which are fed to the chassis via a 5 pin cable. The PSU is capable of powering 2 chassis simultaneously, making this a convenient all-in-one solution that not only supplies robust power but saves you space.
