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.)
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!
