But before even those transistor-based computers is a retrocomputing era rarely touched on: the era of programmable vacuum tube machines. [Mike] has gone back to the 1950s with this computer which ...

A vacuum tube is just that: a glass tube surrounding a vacuum (an area from which all gases have been removed). What makes it interesting is that when electrical contacts are put on the ends ...

Especially in the case of vacuum tube electronics, running down gremlins in the circuits isn’t always a straightforward process (also, please mind the high voltage that is present in old vacuum ...

The history of vacuum tubes in synthesizers goes all the way back to 1939: the Hammond Novachord, one of the first polyphonic synths ever commercially manufactured, relied on an array of 163 ...

But one day, my attention was grabbed by an ad for some headphones. These headphones to be exact — the écoute Vacuum Tube headphones. I’m going to take you through my time with the headphones ...

If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too. The army, with its need for ever-faster and more efficient calculations ...

Do you really need a DAC that costs between $14,000 and $18,000? Bluebird Music thinks the Jadis Vacuum Tube JS5 or JS2 SL are both worth it.

For nearly two centuries, the dream of vacuum tube transport has tantalised scientists and engineers. It is a dream that was reignited by Elon Musk in 2013 with his Hyperloop, which promised to ...
