These Tubes Will Beat Any NOS Tubes! The Best We've Heard! 

The new European-built 12AX7 (ECC-803S) triode tube from EAT is absolutely unbelievable. We have tried them in everything from phono preamps to line stages and amplifi ers. The results have absolutely knocked us out! Built to the tightest tolerances, these tubes are super low noise – dead quiet actually! All tubes are burned-in, then tested to ensure perfect matching and thermal stabilization. The Cool Valve tubes include the EAT Tube Dampers for dissipating vibration, as well. Rated for a lifespan of 10,000 hours, these tubes have beat the pants off our NOS (New Old Stock) input tubes. Expensive but worth every penny… guaranteed!
