Nuvistor characteristics

Michael Dunn <mdunn@...>

Is anyone familiar with the characteristics of Nuvistors? I ask because I do have some data sheets, but the curves don't look like normal tubes or FETs. Instead of a mostly constant-current section, the Nuvistor curves are resistive in nature. The grid voltage seems to modulate the resistance somewhat, and also sets the threshold plate voltage at which the tube starts to conduct! Am I missing something, or are Nuvistors really that different?
