​​HELLO! Many of you know me as CODEMAN015 and now I am happy to say that I am the new owner of Seventh Circle Audio! I have brought back many of the same great designs, using the same high quality components that have always been used in the Seventh Circle Audio products. I have been assembling these products and repairing them since about 2005. Over that time I have assembled and repaired hundreds of these great products! Please feel free to email me at SALES@SEVENTHCIRCLEAUDIO.COM and let me know what products you would like to see! If you need repairs on a product or need a module kit completed visit the support and return policy pages. THANK YOU!




Seventh Circle Audio provides professional quality electronic kits and support to handy audio recording engineers. Our flexible, modular preamp kits provide a full range of "colors" suitable for any application and are in daily use by recordists world-wide.

  • Assemble your own world-class microphone preamp by combining a CH02 or OneShot chassis and up to eight of our superb amplifier modules.

  • Customize your system to suit your current needs and expand as your studio grows. We currently have five preamp modules available, each with its own distinct personality, as well as a 2-channel active instrument DI!

  • Improve your skills as an engineer by learning about electronics, or order fully-assembled units to save time and still save money.

  • Impress your clients with what you can build, not just what you can buy.

  • Save money! Stretch your studio budget by investing your down time in DIY.

Each kit is thoroughly documented with assembly instructions, bills of material and schematics. All the documentation is freely downloadable so you can be ready to go before your kits arrive. If you get stuck or have questions, support is available via e-mail and the message board. We guarantee you won't be stuck with a non-working kit!
