The Radio Tube We Killed in the 1960s Is Now Worth $3 Billion

You knew them by the glow. That warm orange light behind the radio. Behind the television. Behind the hi-fi console where your father played his records on Sunday afternoon. When one went dark, you pulled it out, put it in a paper bag, and took it somewhere to test it. You bought a replacement for sixty cents. You fixed it yourself. You were thirteen. Then you bought a transistor radio. Then a solid-state TV. Then the factories closed. RCA. General Electric. Sylvania. Tung-Sol. Mullard. Telefunken. The tube was declared dead. But it never died. The magnetron in your microwave is a vacuum tube. Military radar runs on tubes. Voyager 1 — 15.8 billion miles from Earth — is still transmitting through a tube that has worked for 49 years. Guitar amplifiers from Fender and Marshall still use tubes because nothing else sounds the same. And in 2022, when Russia banned tube exports overnight, the world discovered just how dependent it still was on a technology it had declared obsolete sixty years earlier. The global vacuum tube market is now worth $3 billion. And growing. You always knew the sound was different. Now the world is paying $3 billion a year to agree with you. #vacuumtubes #radiotube #1960s #electronics #nostalgia #vintage #beforeitvanished #hifi #tubeamp #radioshack
