Testing 300B Tubes, Electro-Harmonix, Sophia Electric and Full Music Brand Tubes

Описание к видео Testing 300B Tubes, Electro-Harmonix, Sophia Electric and Full Music Brand Tubes

This is an unbiased (no pun intended...) set of measurements of a quantity of eight (8), 300B vacuum tube triodes. One quad is made my Electro-Harmonix, another pair is made by Sophia Electric and the third pair is made by Full Music. The Electro-Harmonix tubes were delivered today (4/18/2018) and were never plugged in until this test. I am uncertain of the condition of the Sophia Electric and Full Music tubes before I received them.
Update: The Sophia tubes were still under warranty and the seller replaced them.
