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

Predictably, it was more durable than Whitener thought. It took him two years to persuade AT&T, which hadn’t made a tube since 1988 however nonetheless owned Western Electric, to license the model and promote him its tube-manufacturing tools. He arrange store in Western Electric’s former tube manufacturing unit in Kansas City, Missouri, the place the mothballed machines had been saved.

After a fortuitous assembly with retired AT&T staff on a go to to Bell Labs, Whitener combed the northeast monitoring down veterans of the storied facility, Sylvania, and RCA who knew the arcana of tube-making. When his manufacturing unit began manufacturing of 300Bs in 1996, nearly all of his 20 or so staff had been tube-manufacturing veterans.

Western Electric was up and operating once more, however in 2003 AT&T bought the constructing. Whitener moved the firm to Huntsville, Alabama, a NASA stronghold with expert employees that was handy for his tube contracts with the Department of Defense. In 2008, he moved the firm to Rossville, Georgia. It was there that he started modernizing vacuum tube designs which are greater than 70 years outdated.

Whitener’s group devised a method to apply an atom-thick layer of graphene to a vacuum tube’s anode to lengthen its lifespan by enhancing warmth dissipation and decreasing contaminating gases. Those enhanced tubes hit the market in 2020. Quality management—Whitener’s former area—grew to become extra automated, and he claims greater than 90 % of tubes now move inspection off the line.

Western Electric sells pairs of 300Bs in a cherry wooden presentation field with a certificates charting their efficiency traits and a beneficiant five-year guarantee—yours for $1,500. Copycat units of 300Bs, provided at the similar value, are bought with a 30-day guarantee. Most tubes have a guaranty of simply 90 days.

Whitener has spent greater than a decade getting ready for Western Electric’s subsequent act. In 2006, he received an public sale for equipment and tooling wanted to make 12AX7 tubes; the items had began life in Blackburn, England, however had been then in Serbia. It took 5 years of authorized battles with a competing bidder earlier than the intervention of then-Tennessee  senator Bob Corker and the US Embassy, Whitener says, gave him possession. (Corker, reached by way of a staffer, didn’t dispute Whitener’s characterization.)

Today that tools is being put in on Whitener’s manufacturing unit ground, together with further machines shipped over from Slovakia in 2007. New machines that can automate processes like the hand-bending of wires wanted to make 12AX7 tubes are being peppered in. All the whereas, Western Electric continues to produce 300Bs. Depending on the day of the week, the area might clickety-clack to the sound of a lathe winding molybdenum wire round facet rods, or the ragged hiss of gasoline flames heating and sealing glass bulbs.

Very Pleasant Distortion

The promise of higher sound is, like most issues amongst high-fidelity fanatics, topic to vicious debate. Some hear huge variations between manufacturers of tube, and even particular person tubes of the similar make and mannequin. Others will let you know every tube is indistinguishable from the subsequent. Most agree that tubes on the whole have a sound that transistors, circuit boards, and algorithms can solely approximate, one usually described as heat, wealthy, and even romantic.

“Tubes just distort things in a very pleasant way,” stated Daniel Schlett, a sound engineer whose Brooklyn studio, Strange Weather, is understood for the analog punch it will get from tube-powered mics, amps, consoles, and equalizers. Artists who’ve sought Schlett’s hallmark sound are as various 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.”
