The Telefunken EF806s is considered the best EF86 / 6267 variant on the market. Great for microphones or any other stereo application where the absolute finest detail is required. Manufactured with tight tolerances, these tubes are vibration and shock proof, and the cathode establishes no interface even in cases where the heated tube is operated without plate current over lengthy periods.
