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
- This kit does not come with transformers
This kit is compatible with 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
- Fine-tip soldering iron (temperature controlled recommended)
- Good quality solder
- Small hand tools (flush cutters, pliers, screwdriver)
- Multimeter (recommended for continuity checks)
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.
