DIY Microphone Kits
The products on this page are all-inclusive DIY microphone kits. Just add solder and a few hours' time, and you'll be rewarded with an exceptional piece of audio gear.
We have kits to satisfy all three of the major microphone topologies: transformerless JFET, transformer JFET, and transformer/tube, with 3 different large-diaphragm capsules modeled after the famous European designs.
If you are having a hard time deciding which kit to buy, see our Application Guide.
The S Series: Transformerless JFET
We've hot-rodded the famous Schoeps circuit. Choose this for high sensitivity, low noise, and a clean-and-pristine signal path. The S-series kits (formerly called the "RA-23" kits) are named for the capsule and voicing. See the S-47 (TLM49 voicing), S-12 (C12/C414 voicing), and S-87 (U87 voicing), below.
The S3 Series: Multipattern Transformerless JFET
We've taken all the sonic magic of our acclaimed S series circuit, and added two external switches. The switches enable a 10dB pad, and a 3-way pattern selection (Cardioid/Omni/Fig8).
Looking for mid-side or Blumlein? The S3 has you covered.
The S3 series maintains the same high sensitivity, low noise, pristine signal path of the S series, built into a robust body. The S3 kits include a hard case and shockmount.
The T Series: Transformer-coupled JFET
We've recreated Neumann's KM84 circuit, then optimized it for large-diaphragm capsules. The result is a spectacular vintage-circuit microphone with an extraordinarily simple signal path and a ton of texture. Choose this for vintage vibe.
The V Series: Transformer/Tube
Our tube mic is an adaptation of the Telefunken ElaM 251 circuit, although with higher headroom. We use a low-noise tube and a custom-wound transformer. The finished mic competes with commercial boutique offerings in the $1500-$2000 range.
See also our custom tube mic power supply, which is available as an upgrade option for both these microphone kits.
Why These Kits are Superior
You might have seen other DIY microphone kits that are comprised of indifferent, low-grade parts and a photocopied schematic that supposedly serves as the installation guide. The products on this page are in a different league -- as are the finished microphones. We use parts equivalent to what you'd find in commercial microphones costing over $1500.
