Origins of the Kit1

The Audio Note Kit1 became an instant hit when it was launched back in the 1990’s and introduced hundreds of audiophiles to the sound of single ended 300B zero feedback. It is a favourite at ANK Audiokits, and we have continued enhancing the kit with each production run. The original Manual was written by Peter Q which we have upgraded with colour graphics and wiring diagrams.

The 1.7mm thick steel chassis was upgraded to 3mm aluminum, enhanced filament heat sinks and valve bases where added, a new faceplate, selector switch options, Takman Resistors on the standard version, plus insert plate in stainless steel or copper rounds up the enhancements to the Kit1.

Enter the Kit1-10th – the ultimate version of the Kit1

To celebrate the wonderful history of the Kit1 we released the Kit1-10th Anniversary Limited Edition with triple C-Core output transformers, Takman Resistors, ELNA Cerafine Caps and Mundorf Silver Oil Film Caps. The amplifier has the option of an Elma selector switch with 3 inputs.

An extraordinary version of this amplifier – we believe it is sure to be a collectors edition for years to come! To hear what a Kit1 is truly capable of, you have to hear the Kit1-10th variant, it is a revelation.

Kit1-10th circuit layout

Signal paths are kept to the absolute minimum and the boards layout has been designed for ease of assembly and soldering.
