Nuvistors are pretty cool for some jobs, even today.

Out of curiosity, like what?
 
 
 

They have about a 2-dB noise figure out to 500ish MHz, iirc, and a
combination of low capacitance and high voltage capability that is very
difficult to match with semiconductors.

That makes them very good for the sorts of HV diff amps JL was talking
about, or so I believe. (The last tube circuit I designed was in about
1990, and it didn’t use Nuvistors. )
