(#233665498854). Hello tube museum. Just got the tubes from you. BEST SOUNDING, BEST MADE and MOST VALUABLE and RARE out of ALL the EF86 Amp and Audio tubes. The classic EF86 pre-amp tube is remarkable for its high gain and for the notable harmonic overtones it produces and feeds to the power tubes when driven into distortion, providing the creamy distinctive VOX sound of the early hand made amplifiers produced by Jennings of Dartford.
