Has anyone ever made a guitar amp with nuvistors?

I haven't, but I have several set aside for a couple of projects. The first time I ever saw one, it was years ago in an old tektronix plugin type module like this:



I thought they were some kind of weird power transistor I hadn't seen before. I compiled a file with all the transfer characteristics of the ones I have.

As for the NuTube, I had high hopes in anticipation of it's release. But after getting a hold of the datasheet, I wondered why they bothered ever going into production. The gm, gain, and input impedance blooooooooooow, compared to any other discrete amplifying device I can think of. Even in the miniature class of tubes, Nuvistors and Subminiature tubes perform so much better. I like the idea of what they were going for in the physical package design, but what a let-down.
