RCA published a really nice cutaway drawing with annotations.

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.)

@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!
