Golden Age Premier GA-8000 PSU – Microphone Power Supply

OVERVIEW

The GA-8000 PSU is a replacement power supply for the Golden Age Premier GA-8000, Golden Age Premier GA-800g, and Sony C-800G microphones.

As a modernized update to the classic power supply, forgoing tube rectification in favour of solid state, the GA-8000 PSU also includes an FET-based stabilizer for the high voltage rail. Golden Age Audio has employed star-grounding techniques to better optimize the signal-to-noise ratio beyond the spec of the original. Finally, GA has leveraged audiophile-grade PCB design techniques, including massively oversized copper traces for maximum electrical transmission, and Elna capacitors for reduced microphonics and vibration.

The result is a smooth, natural capture of the source sound with improved signal propagation speed and lower equivalent series resistance (ESR), which improves efficiency, reduces heat, and extends the lifespan of the capacitor and related components.

Rigorous listening tests convinced the Golden Age Audio team to choose a solid-state rectifying circuit over the tube-based approach of the original design. The solid-state architecture won by a landslide sonically – with the added benefit of removing long-term maintenance cost and hassle with no need to replace tubes.

The GA-8000 PSU is compatible with the following microphones:

• Golden Age Premier GA-8000
• Golden Age Premier GA-800G
• Sony C-800G

Get the most out of your microphone investment with the GA-8000 PSU. You’ll be glad you did!
