I'm trying to gain some understanding of how early computers were built; as discussed in What accounted for the cost of ENIAC? the cost of first-generation computers was not necessarily mostly about the cost of purchasing the components; much of it was about the costs of assembly, testing and suchlike.
In later decades, printed circuit boards came to be heavily used, but as I understand it, not only had they not yet been invented in the forties and fifties when vacuum tubes were most heavily used, but PCB materials do not stand up well to continual exposure to concentrated heat sources like, well, vacuum tubes.
Wire wrap was used in the transistor era, the sixties and seventies, not just for prototyping, but also for manufacturing. It would seem on the face of it to be suitable for vacuum tube computers. On the other hand, I found this discussion: https://www.diyaudio.com/forums/tubes-valves/287205-vacuum-tubes-wire-wrap.html in which a poster suggests wire wrap and vacuum tubes do not mix:
However, after much experimentation, it became clear that wire wrap was only good for the short term, by itself. If the piece of built-stuff flexed much, then eventually oxidation would set in and make some one of the hidden dozens-to-hundreds of connections vexingly noisy. And never when debugging.
That would seem to leave vacuum tube computers to be constructed by 'point-to-point construction' which seems to be the technical term for 'just solder all the components individually'.
This is counterintuitive; it feels to me like wire wrap should be more resilient than soldered joints, therefore better able to withstand thermal cycling. But I'm no electrical engineer; my intuition might be wrong. And while I can find plenty of mention of transistor computers being built (for production, not just prototyping) with wire wrap, I cannot find any mention of vacuum tube computers being so built.
Were any vacuum tube computers built with wire wrap? If so, did it work reliably? If not, why not?
