One Man’s Quest to Revive the Great American Vacuum Tube (Wired)

The prized retro audio components are mostly manufactured in Russia and China. Now, a small Georgia company is rebooting US production.

ROSSVILLE, GEORGIA, ON the border with Tennessee, doesn’t look like a tech town. It’s the kind of place where homey restaurants promising succulent fried chicken and sweet tea are tucked among shuttered businesses and prosperous liquor stores. The cost of living is moderate, crime is high, politics are red, and the population has withered to 3,980.

But in the view of entrepreneur Charles Whitener, Rossville is the perfect place to stage a revival in US technology and manufacturing—albeit with a device that was cutting edge when the Ford Model A ruled the roads.

Whitener owns Western Electric, the last US manufacturer of vacuum tubes, those glass and metal bulbs that controlled current in electric circuits before the advent of the transistor made them largely obsolete. Tubes are still prized for high-end hi-fi equipment and by music gear companies such as Fender for their distinctive sound. But most of the world’s supply comes from manufacturers in Russia and China, which after the transistor era began in earnest in the 1960s helped sunset the US vacuum tube industry by driving down prices.

Whitener, a 69-year-old self-described inventor, vintage hi-fi collector, and Led Zeppelin fanatic, bought and revived AT&T’s shuttered vacuum tube business in 1995. The business has ticked along in the era of cheap overseas tubes primarily by serving the small market for vacuum tubes in premium hi-fi equipment with a model called the 300B, originally designed in 1938 to enable transoceanic phone calls.

Many rely on radio broadcasts in Zimbabwe and across Africa (Northwest Arkansas Democrat Gazette via AP)

Many still rely on radio broadcasts for news, entertainment across continent

HARARE, Zimbabwe — Just the size of his hand, the radio set hung in the busy marketplace stall is essential to Mark Nyabanda.

“I can’t do without it,” said the 25-year old, taking a break from selling fertilizer in Mbare market in the capital, Harare, to listen to a radio weather report warning of possible floods.

Radio bulletins also provide him with information on disease outbreaks, political news and entertainment, he said.

“I don’t trust these new technologies,” he said, referring to social media. “They are full of falsehoods. We saw it during the coronavirus outbreak.”

In many Western countries, conventional radio has been overtaken by streaming, podcasts and on-demand content accessed via smartphones and computers.

But in many of Africa’s 54 countries, with a combined population of 1.3 billion people, traditional radio sets are widely used, highlighting the digital divide between rich countries and those still struggling to have reliable internet.

Radio sets are all over the place in Zimbabwe. Rural livestock herders dangle them from their necks while tending animals while those in the cities listen to their radio sets for news. [Continue reading…]

    Suggest you listen to your system with Audience 24 SX cables,phonoi inerconnects and speaker wire. If it sounds the same to you,then you need better hearing aids,etc. Peace out, Happy Easter PS:been into high end audio since 1973, was a side business for 30 yrs

    Most professional recording studios use vacuum tubes in their preamps, compressors and microphones.

    Some of these tubes (“valves” if you’re British) haven’t been manufactured in decades and are now expensive and hard to get.

    For example, the Telefunken VF14 vacuum tube in the Neumann U47 microphone sells for around $3,000:

    There is a small company based in the UK Midlands who are starting to manufacture radio valves.

    It seems to be rather based on a shoestring because they were trying to recruit volunteer workers. Although with the number of retired electronics engineers around they may be somewhat successful in this respect.

    By coincidence, for about a year before I joined the BBC, I did actually work at the GEC MO Valve Company at Chiswick. That was very interesting as they made small runs of specialist valves and CRTs.

    As a 65+ year old audiophile, the Wired article was a good read. Tubes are the way, for sound. There are other elements at play though, such as when audiophiles start believing things sound different, even though they are exactly the same. If you really believe that a $200.00 electrical outlet, turntable dampening feet, or a 6 gauge wire versus an 8 gauge wire sounds better, please drop me a line, as I have a lot of other junk .. .. I mean audio gear, to sell you.
