    Fantastic tubes!

    Great tubes, take about 60 hours to burn in properly, but sound really nice well worth it.

    Отличные лампы. Покупал на замену EL34. Замена полностью оправдалась.

    Отличные лампы. Покупал на замену EL34. После установки прислушивался к ним неделю. Оптимизировал параметры (повысил анодное напряжение и ток покоя). И вот оно, случилось. Даже не ожидал такого улучшения. Прям Hi-End, какой то! Солидные низы, четкие высокие и завораживающие средние. Рекомендую эти лампы всем любителям лампового звука и разработчикам, сборщикам усилителей.
