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.
Brand New Matched Quad (4) Svetlana 6550 / 6550C (KT88) Reissue Vacuum Tubes
There is a lot of confusion when it comes to the legendary Svetlana 6550 tube and we want to clear it up. These are technically reissues though they are built in Russia using the same equipment as the originals. In the early 2000's New Sensor bought Svetlana and they are made in the Saratov plant now rather than the original Saint Petersburg plant. Other than where they were made, they are no different than the original 1990's SED or Winged =C= 6550 tubes.
These are some of the finest new production 6550s money can buy. They're known for their robust quality and classic American 6550 tone.
