One Man’s Quest to Revive the Great American Vacuum Tube*
*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.

But recently US trade restrictions on Russia and China, over the
former’s renewed invasion of Ukraine and the latter’s ideological
disputes with Washington, have sent vacuum tube prices soaring. At one
point in 2022, tubes that typically retailed for $10 were offered at
prices over $100, says Daniel Liston Keller, who does public relations
for recording industry clients. Although shipments of Russian tubes have
resumed, prices remain high and the quality of overseas tubes has always
been unreliable. “You have to buy 100 tubes to get 30 you like,” says
Justin Norvell, an executive vice president at Fender. An affordable
tube for a guitar preamp is now roughly $30, meaning the company can
spend about $90 to get one tube that meets its standards.
Whitener has seized on the current moment of high prices as a chance to
reinvigorate his company, the US tube industry, and even the idea of
what a vacuum tube can be. Western Electric is currently working on a
modernized tube design, an iteration of the all-but-obsolete technology
fit for the 21st century. It’s an improved version of a tube called the
12AX7, which is common in guitar preamps and other music gear—a market
Whitener estimates is more than 10 times the size of the premium hi-fi
business and is today served almost wholly by overseas suppliers. The
recently high prices create economic cover, he calculates, to make a
better version in Rossville that can be more reliable, durable, and
economical than existing designs, turning the US into a powerhouse of
vacuum tube technology again.

That makes Western Electric an oddball member of the swelling movement
to bring technology manufacturing back to the US, assuring the supply of
crucial products, such as computer chips and electric vehicle batteries,
that are generally sourced overseas. The company is in the process of
restructuring its factory floor with a combination of vintage and new
machinery to turn out the modernized tubes, at the volumes Fender and
other music companies need.
Whitener is a perfectionist. He aims to launch the 12AX7 this summer,
but previous debuts have slipped. His factory is poised to make America
the dominate source for audio vacuum tubes, improving the fortunes of
Rossville, audiophiles, guitar heroes, domestic manufacturing, and
Whitener himself—if he can just get the damn things out the door. “This
landscape for the Russian tubes could change tomorrow,” he concedes.
“It’s a Walmart world, and that’s a risk.”
*How Hard Can It Be?*
From the 1920s through the 1950s, the American vacuum tube industry
thrived. RCA, General Electric, Raytheon, and other manufacturers
competed to invent and manufacture more reliable tubes, which were
needed to regulate current and boost the faint signals from analog
microphones and instruments enough to drive speakers. But the arrival of
transistors, then circuit boards, made tubes obsolete for most uses.
American manufacturers couldn’t match prices from overseas. Factories
closed. Engineers moved on.
Many musicians and audio obsessives stayed loyal to the tube but
increasingly got them from outside the US. Russia and China became the
leading suppliers, with companies such as Shuguang Electron
Group cranking out tube designs established between the 1930s and 1950s,
such as the 6L6 and EL34.
By the time Charles Whitener took a career break in 1990, the US did not
make any consumer audio tubes. He thought about changing that after
noticing a steady stream of ads in hi-fi magazines offering Western
Electric 300Bs, a design from 1938 that was popular with audio
enthusiasts. Whitener was looking for a new venture after using his
experience in his father’s yarn factory to invent a quality control
system for the fiber optics industry that he then sold. “I thought, how
hard can it be to make these tubes?,” he says. “People are willing to
pay $1200 to $1500 a pop for them.”
Predictably, it was harder than Whitener thought. It took him two years
to persuade AT&T, which hadn’t made a tube since 1988 but still owned
Western Electric, to license the brand and sell him its
tube-manufacturing equipment. He set up shop in Western Electric’s
former tube factory in Kansas City, Missouri, where the mothballed
machines were stored.
After a fortuitous meeting with retired AT&T employees on a visit to
Bell Labs, Whitener combed the northeast tracking down veterans of the
storied facility, Sylvania, and RCA who knew the arcana of tube-making.
When his factory started production of 300Bs in 1996, almost all of his
20 or so employees were tube-manufacturing veterans.
Western Electric was up and running again, but in 2003 AT&T sold the
building. Whitener moved the company to Huntsville, Alabama, a NASA
stronghold with skilled workers that was convenient for his tube
contracts with the Department of Defense. In 2008, he moved the company
to Rossville, Georgia. It was there that he began modernizing vacuum
tube designs that are more than 70 years old.
Whitener’s team devised a way to apply an atom-thick layer of graphene
to a vacuum tube’s anode to extend its lifespan by improving heat
dissipation and reducing contaminating gases. Those enhanced tubes hit
the market in 2020. Quality control—Whitener’s former field—became more
automated, and he claims more than 90 percent of tubes now pass
inspection off the line.
Western Electric sells pairs of 300Bs in a cherry wood presentation box
with a certificate charting their performance characteristics and a
generous five-year warranty—yours for $1,500. Copycat sets of 300Bs,
offered at the same price, are sold with a 30-day warranty. Most tubes
have a warranty of just 90 days.
Whitener has spent more than a decade preparing for Western Electric’s
next act. In 2006, he won an auction for machinery and tooling needed to
make 12AX7 tubes; the pieces had started life in Blackburn, England
<https://www.youtube.com/watch?v=GDvF89Bh27Y>, but were then in Serbia.
It took five years of legal battles with a competing bidder before the
intervention of then-Tennessee senator Bob Corker and the US Embassy,
Whitener says, gave him possession. (Corker, reached via a staffer, did
not dispute Whitener’s characterization.)
Today that equipment is being installed on Whitener’s factory floor,
along with additional machines shipped over from Slovakia in 2007. New
machines that will automate processes like the hand-bending of wires
needed to make 12AX7 tubes are being peppered in. All the while, Western
Electric continues to produce 300Bs. Depending on the day of the week,
the space may clickety-clack to the sound of a lathe winding molybdenum
wire around side rods, or the ragged hiss of gas flames heating and
sealing glass bulbs.
*Very Pleasant Distortion*
The promise of better sound is, like most things among high-fidelity
fanatics, subject to vicious debate. Some hear vast differences between
brands of tube, or even individual tubes of the same make and model.
Others will tell you each tube is indistinguishable from the next. Most
agree that tubes in general have a sound that transistors, circuit
boards, and algorithms can only approximate, one often described as
warm, rich, or even romantic.
“Tubes just distort things in a very pleasant way,” said Daniel Schlett,
a sound engineer whose Brooklyn studio, Strange Weather, is known for
the analog punch it gets from tube-powered mics, amps, consoles, and
equalizers. Artists who have sought Schlett’s hallmark sound are as
diverse as Ghostface Killah, Booker T. (of MGs fame), and The War on
Drugs. “Tubes are part of the equation,” Schlett says. “It’s big and
amplified, and it has the voodoo on it.”

But voodoo is exactly the problem, say tube skeptics like Glenn Fricker,
an engineer of 25 years who specializes in metal bands at Spectre Sound
Studio in Ontario, Canada. He sometimes uses a 1966 amp with its
original tubes, but he doubts expensive replacement tubes would improve
the sound.
“As a kid we are led to believe there is some dark art in tubes which
will inherently change the sound of your amp,” Fricker says. But when he
devised an experiment using sound canceling
<https://www.youtube.com/watch?v=VaO7MmghoqA> to reveal the audible
differences between tubes, all he uncovered was “a little clicking
sound”—they were otherwise identical. He advises guitar slingers to skip
the $1,300 vintage Telefunken “Diamond Bottom” 12AX7 online at Tube
Depot for the $20 JJ brand from Slovakia. While Fricker is rooting for
Western Electric, he says, “Are they going to sound any better than your
dear, cheap JJs? No.”
Price spikes during the recent great tube panic suggest plenty of people
still believe in the voodoo. That presents Whitener with an immense
opportunity. He says he aims to launch Western Electric’s 12AX7,
America’s first new tube in decades, this summer. After that he plans to
add a string of additional models, versions of the 6L6, EL34, EL84 12
AT7, and 6V6 tubes—a lineup he calculates makes up almost 80 percent of
the relevant music equipment, such as guitar and studio amps. If all
goes to plan, the US could once again dominate vacuum tube manufacturing.
Whitener concedes that he’s taking a big risk. Russia looks determined
to keep attacking Ukraine, keeping trade embargoes in place, and
China-US relations remain tense. But the geopolitics of vacuum tubes
could shift again. It’s unclear how loyal people might be to his US-made
tubes.
Whitener hopes that even if international supply prices drop, customers
will stick with Western Electric after having gotten a taste of the
reliably durable tubes. “They are looking for a stable product they can
count on,” he says. Schlett, the sound engineer, is hoping Whitener can
deliver. “My advice is please, quality control, please, please, please,”
he said. “I don’t want to throw out 70 percent of the $180 tubes I buy.
That’s not OK.”
