Years ago there was a small tube called the Nuvistor. Looks like these guys were trying to reinvent the wheel.

Thanks for that link. It seems to have the same horrific distortion of the one I tested:I built Pete Millet's Nuhybrid Headphone amp, if you're interested in measuring a different product with this tube.
...but I am open to more feedback...

I don't think it is worth sending it back and forth but I am open to more feedback.
So we have one cute little distortion box.
I bought the kit to build the Pmillet Nutube hybrid.I have a different nutube headphone amp and if I so much as brush against the headphone cord I get a ringing sound from it. I guess I got an extra microphonic nutube.
I don't have any power hungry headphones so I don't really need an amp, I just like building things but I quit using it because of the ringing.
I like tubes but I'm not a fan of adding them into a circuit just for the 'sound'.

Many thanks for introducing me to this flabbergasting product! I watched the video in amazement as well, it seems you have to unscrew the whole front to replace the batteries.
Nothing seems to be too far fetched in esoteric hifi products.
It has inspired me with a product idea. Why not make fake tubes with led's in them? You could construct a class D amp with "tube sound" filter and power the whole thing over usb. Or maybe such a product already exists...
Musical Fidelity came out with a number of "Nu-Vista"-based components, including DACs and preamps. They claimed they had bought all the nuvistors in existence (and then doubtless went on to corner the market in Siberian tigers), which made me wonder why I'd buy one of their products since they claimed they were the only game in town for replacement nuvistors.
Behold: https://www.musicdirect.com/integrated-amp/musical-fidelity-nuvista-800-integrated-amp $12,000 for an integrated amp that they claim outputs 330 watts per channel into 8 ohms.
Pass.
I like tubes too, but why would you add them to a circuit if not for the ‘sound’?

Entertainment. I often analogize it to driving an Avanti or a T-Bird instead of a Lexus. It won't get you there any faster, but it can be fun if that's your mindset.
