Wax nostalgic about and learn from the history of early electronics. See articles from Electronics, published 1930 - 1988. All copyrights hereby acknowledged.

According to the somewhat limited unique information (much repeated, as I'm doing here) available about the "nuvistor" vacuum tube amplifier, it was superior to many glass-encapsulated vacuum tubes. Lower noise figure, smaller size, greater ruggedness, intrinsically shielded, and relatively higher operating frequency (near a gigahertz) were the main marketing standpoint. RCA introduced the nuvistor in 1959, and shortly thereafter General Electric (GE), started making them, and then by 1964 (maybe earlier) Hitachi was offering nuvistors. The manufacturing process, where the entire assembly was performed in a vacuum chamber, made nuvistors more expensive than competitor glass tubes. The nuvistor concept might have been big if semiconductors (transistors) had not been making such rapid progress in supplanting most vacuum tubes. In fact, nuvistors (a portmanteau of "new" and "transistor") were supposed to tamp down interest in transistors, but history shows the winner in that contest.

Nuvistor, National Valve Museum - RF CafeA nuvistor was used in the front end of the HP3400A True RMS Voltmeter (thanks to Michael M. for that). Also, thanks to Bob Davis for pointing out that the Lafayette HB-400 CB radio sported a Nuvistor in the receiver front end. Here is a Nuvistor info resource. See the "Nuvistors and Micro-Modules," "The Tube Family Tree," "Lafayette Radio Electronics," "Hitachi Nuvistor Ad," "Using the Nuvistor on V.H.F. Bands," and the "The NASA 136" articles, too.
