Visit our store to view our inventory of thousands of tubes. We are an authorized dealer for New Sensor products including Sovtek, Electro-Harmonix, Mullard, Tung-Sol and Genalex. We sell A grade quality stock, not factory seconds like many other sellers. You may notice other sellers listings these at a lower price. New Sensor increased the price on all of their tubes this year. Anyone selling their tubes below market value is selling old stock that will run out at that price or B-stock. These are fresh tubes.
