The AUSTIN Mic Pre (AMP) Kit is TEMPORARILY SOLD OUT – December, 2023.
We are redesigning the enclosure and will have an update around January, 2024.

The Austin Mic Pre(AMP) kit is our Do-It-Yourself preamplifier kit designed especially for Austin Ribbon Microphones. No fancy lights, meters, or phantom power… This is a dedicated, world-class ribbon microphone preamplifier that YOU build.

The Austin Mic Pre (AMP) is a complete DIY kit with a fully-illustrated step-by step instruction tutorial – just like my Austin Ribbon Microphones – and includes everything down to the hex key for the knob and a static wrist strap for handling the semiconductors. It’s a kit designed to help you improve your soldering skills and breadboarding skills. Some previous soldering experience always helps, and you need a soldering iron, solder, wire strippers, and a few basic hand tools like a screwdriver and pliers.

Designed with state-of-the-art circuitry, and premium audio components, the Austin Mic Pre (AMP) delivers excellent performance over the entire audio spectrum… and beyond. Its 11 gain stages range from 10dB to 72dB in 6dB steps, and deliver a whisper-quiet -135dBvA EIN, with just .0067% THD+N at +19dBV out. It can be assembled in 4-5 hours.

These are are USA kits, made in San Diego, CA.
The Austin Mic Pre (AMP) is not an imported kit, repackaged and marked-up. Each kit is hand-picked audiophile components, bagged by me in my workshop with locally machined and laser-engraved panels that don’t rub-off.
The Austin Mic Pre (AMP) Features Mogami® internal wiring, Neutrik® connectors, a beefy 1 -Amp power supply, and a heavy duty tinned-through-hole circuit board, not cheap single-sided perf-board.

Photographed and illustrated at every step (more than 60 photos & illustrations total!) the Austin Mic Pre (AMP) is an easy weekend project for intermediate, electronic project DIY’ers.
