At the Burning Amp Festival in 2017 Nelson presented a pre-amp using the Korg Nutube dual triode. The latest revision of the circuit available is now available complete with Fairchild JFETs and all directly supplied by Nelson Pass. 

Please check the following links for more information:

There are 4 elements to building a complete preamplifier. Purchase the elements separately, or all together as a "full kit" bundle for $299. To build a complete preamplifier you will need:

  1. Nutube ($49.99)
  2. PCB + JFETs ($25)
  3. Chassis ($129)
  4. Completion Kit ($99)

What's in the completion kit?

Everything else you need to complete the project other than 1, 2 and 3 above. It's an assortment of bits and pieces that joins the Nutube, PCB and Chassis together, turning the whole things into a "full kit", hence the name "completion kit". 

The included "wall wart" style power adapter supports an input voltage of 90-264V and has a US style plug. If you don't live in the US you will need to obtain a suitable plug adapter.

What are the chassis specifications?

  • Galaxy 230x170 full aluminum chassis, anodized black with white printing
  • Internal dimensions 40x210x170mm
