ROFL!!!

400 million the year I was born? And that's just US production? I look at my collection and feel like I'm slacking.

You have just 1% of those?

1960 is a good year. The year of the RAT .

If you deduct all the tubes @Wes S has bought and socked away, that should leave a couple of dozen for the rest of us

LOL! I definitely have a problem.

... you're not slacking ... at your age, forgot where your auxiliary hoards are located ...

Geez, that is a depressing chart - fully shut down before I even existed

Not that depressing - General Electric produced their last batch of 6550s back in 1985.

Seriously. And my parents got me a Tonka Truck when I asked for a case of 300Bs.

One of my favorite Hi Fi stories was written up in Stereophile. Way back then someone drove around the country and picked up old Western Electric horn speakers and amps from defunct movie theaters. When his crew was bored they practiced target practice on used Western Electric 300B tubes...

What a shame!

What a shame!

When the writer asked why they are shooting down the tubes, they answered: But they are used tubes...
Perhaps they did not know that the Western Electric 300B are rated for 40,000 hours.

But they were shooting photons from the ACME laser pistols. And still missed.

Many tubes that audiophiles covet today were probably replaced on schedules regardless of how they measured and then thrown out. They were ubiquitous, consumable products and better to maximize uptime than to worry about eking every last hour out of them. I'm thinking about radio, power supply, and telecommunications applications. Then there were the early computers. I shudder to think how many primo 6sn7 tubes were churned through running those beasts.
