E.A.T. E-Glo I integrated amplifier

While studying for her MBA at the University of Economics in Bratislava, Slovakia, Lichtenegger (née Krahulkova) sold vacuum tubes for her brother-in-law, Alesa Vaic, then owner of Czech Republic–based tube brand VAIC. After VAIC shuttered in 2003, Lichtenegger founded her own retail business and engaged 100-year-old tube manufacturer Tesla Vršovice to supply 300B and KT88 tubes made to her specifications. When the owner of Tesla retired, she bought the company. She christened her new endeavor E.A.T. (The original Tesla continues as TESLA ElectronTubes, s.r.o.)
