Nowadays the dump is called eBay.
That's where new production tube rejects go.
After they've been sold & returned of course.

Considering QC then and now, it's a shame so many of those Sylvanias (and RCAs and GEs and Philips) went to the dump. I think I could work with a lot of them.

This would now be considered a textbook example of a toxic waste dump. :?

I'm surprised people aren't trying to dig it up like Capt. Kidd's treasure. If that ever happens look out for a shit tsunami on ebay. But, yes it's only rock'n'roll, I'd take a wheelbarrow of reasonably off spec ones.

I also what to get an old flattened cardboard box and sled down that tube hill!

Mostly not, I would say, since only specialized tubes used thoriated tungsten. The vast majority of this pile would likely have been receiving tubes which used pure tungsten filaments with oxide coated cathodes.

Boasting of your reject rate is an interesting idea...

Late 70's the top-line Grado phono cartridges, $750 at the time, were personally tested by Joe Grado. Those that didn't pass his audition weren't sold as "seconds." He put hammer to 'em right then and there. So he said when he gave a lecture/demonstation at the local stereo shop.

What percent passed or failed, who knows. But I have to admire Joe's commitment to perfection. FWIW Grado's cheap cartridges, only $20 at the time sounded pretty dam' good.

Seriously though, did they really just plow them under as the photo suggests? Were we ever that stupid?

Oh yeah, the battery factories. We were that stupid.

I'm not much of an environmentalist, but manufacturing practices back then appall me.
