Doesn't this possibility periodically revive itself, at least in
press releases? That some jobs are still done well by vacuum tubes
and not silicon?
As a kid, I spent a lot of time harvesting junk from the back
of TV repair shops. (Yes, back in the day when we fixed TVs, kids.)
So I have a visceral affection for metal in glass. I remember
breaking the tubes and extracting the little rings holding
the 'getter', which was calcium carbide.
Most recently, I had a tour of a small radio station by the old
engineer who kept it running with spit and baling wire. I was
envious of his nice collection of old huge tubes from the transmitters
he'd worked on. Let me guess. I can buy similar tubes on eBay?
