The MC1 DIY kit is a complete parts pack to build your own step-up transformer preamp for moving coil (MC) cartridges. Used between your turntable and a standard MM phono input, a properly designed SUT increases signal voltage passively while preserving the low-noise, dynamic character that makes transformer coupling so compelling.

This kit follows the same design intent as our assembled MC1 units - robust mechanical grounding, reliable switching, and a layout that’s built for consistent real-world results.

What's included

• Aluminium enclosure with black front panel
• Gold-plated PCB
• Gold-plated RCA connectors
• High-quality switches
• Grounding lug / hardware
• Resistors and capacitors required for the circuit
• Mounting hardware and essential build items required to complete assembly
• Transformers, if purchased together

This kit is compatible with all Lundahl moving coil step-up transformers. 

Skill level

This is a straightforward DIY build, but it is not a “first soldering project.” We recommend prior soldering experience, as the parts are high quality and can be damaged by excess heat or poor technique.

Tools you'll need

• Soldering iron (temperature controlled recommended)
• Good quality solder
• Small hand tools (flush cutters, pliers, screwdriver)
  

Note on responsibility

This is a DIY kit. Assembly, testing, and safe operation are the builder’s responsibility. If you are not confident with soldering and basic electronics handling, consider an assembled unit instead.

Transformer stock

We stock a large variety of transformers, however there may be a 4-8 week wait on some types as they might need to be ordered in especially. Please get in touch before purchasing if you have any questions.
