I thought some of those automated machines were amazing considering the era.
Could you imagine the cost of setting up a plant like that today?

We are all pretty lucky to have lived through the era of tubes and of course some of the best music they helped produce.

In one of the video's when they panned through an assembly area it is was 90% +/- female. Pretty cool.

Those test area's were great, all of those huge meters!

Fantastic - Thanks Trout.

The cost of setting them up must indeed have been huge - but then so is a microprocessor fab (and valves were the core2duo of their day...) - it is the margins on the products that allows the companies to invest so heavily in the production tech.

Setting up a Valve plant today must be just about impossible, without the huge base of knowledge and experience in designing both valves and the mechanical equipment necessary to mass produce them.

The open-air sprays of Strontium and Barium were, erm, interesting.:eek:
