> tubes, my retirement income
I bought lots of tubes when they were new, some for 64 cents instead of investing in gold.

It’s funny, they learned how to make artificial diamonds for cheap, but forgot how to make tubes. So I’m glad I didn’t invest in diamonds back in the 50s.

Compared to the tube heyday, no, nobody is making them. It’s not even round-off error. Go into your local independent drugstore, and ask them where their tube tester is, because you need a new RCA 845 and pick one up if the one you removed to bring in tests bad.

Like, technically, the magnetron in your microwave is a metal-can tube, and so is the neon indicator in your extension cord, but these are very very different.
