Tube🌿Timefeast your ocular orbs on this cross section of a miniature Nuvistor vacuum tube.
and here is the Nuvistor, flanked by a "miniature" vacuum tube on the left and a transistor from the same era on the right. RCA's Nuvistor was just a micro-miniaturized vacuum tube they felt could beat the transistor. (it did not.)
Karl Matthias 🇺🇦@tubetime never heard of this before. So cool.
Pheedback Phil@tubetime my parents threw out my nuvistor and valve collection while I was at university in th 1980s ☹️. Nuvistor kit would have survived EMP effects from atom bomb much better than transistor kit as I understand it, which was something on our minds back then!
Mike Prior-Jones@tubetime I dimly recall someone selling very expensive nuvistor-based hifi amplifiers in the 90s, back when there was still cachet in valve amplifiers
@tubetime found it: https://ebay.us/m/fGBNTd
Still very expensive!
bitsavers.orgCheck hamfests if people want to find some. They were used in early 60's Motorola PT-100 Handie-Talkies

✧✦Catherine✦✧@tubetime damn I want one so much now
Григорий КлюшниковYou know what I'm curious about? What would happen if technologies like this continued getting developed, of course. We have MEMS chips now, stuff like accelerometers and such, with precise microscopic parts with voids between them. Could this technology be used to manufacture microscopic vacuum tubes?
Paul@tubetime wow! Impressive cutaway skills! (How?!?).
For whatever reason, I found nuvistors to have a much shorter life than their larger glass counterparts. When repairing Tektronix 560 series plugins, they’re a common source of trouble. I wonder if that’s just because the cathodes are so much smaller that they loose emission sooner?

glasspshr@forty2 @tubetime when I was at the Smithsonian decades ago the had a Nikon F exquisitely sawed in half. I know not how
Here’s a pic of a Nikon F2 sliced in half
aeberbach@glasspusher @forty2 @tubetime if you are interested - complex things cut in half was probably done with a https://en.wikipedia.org/wiki/Water_jet_cutter
Norman Wilson@tubetime Peanut tube! I've got one somewhere in a miscellanous-junk box. Just in case.

Anthony, of course
ramblingsteve@tubetime cool. Needs some forbidden planet background audio.
