Any tubes currently manufactured in the US, Japan or Germany?


Just curious. This looks interesting, I wonder if we may see something like this in the future

The NuTube has been around for a while. It was developed to provide a way to add low order harmonic distortion for Korg’s synthesizers. It is somewhat popular in the DIY community and their are a number of designs available including one from Nelson Pass.

The big disadvantage of this product is that it is extremely microphonic, but it does do a nice job generating second order harmonics.
