D-12 Microphone Power Supply (PSU)

This D-12 microphone power supply is designed to provide stable, reliable operation for D-12 tube microphone builds. Supplied fully assembled and tested, it operates out of the box, making it an ideal solution for first-time builders as well as experienced DIYers looking for a dependable starting point.

The standard PSU features a zener-regulated 120 V rail, delivering consistent performance and low noise suitable for studio use. Its proven topology ensures safe, predictable operation and allows builders to focus on microphone assembly and voicing without additional power-supply complexity.

For those seeking further refinement, the PSU supports a clear upgrade path. The optional D-12 PSU PCB introduces enhanced passive regulation of the 120 V rail, resulting in a lower noise floor and improved overall performance once the base build is complete.

An excellent choice for powering D-12 microphone projects, offering reliability, simplicity, and the flexibility to evolve as your design ambitions grow.
