Sophia Electric Blue Glass 6SN7 Tubes
This blue glass 6SN7 tube delivers rich tonality and big soundstage, designed to complement Aqua 274B and Classic 300B tubes. It is an excellent choice for replacing both current and vintage 6SN7 tubes in all tube pre-amplifiers and tube amplifiers.
The 6SN7, like all dual triode tubes, contains two sections. Achieving a close match between these two sections is already challenging, but matching two tubes—four sections in total—becomes even more difficult when applying a high standard of matching.
Note: Some internet vendors only test one section of the tube due to the limitations of their vintage tube testers, such as the popular TV-7. As a result, tubes claimed to be matched may be based on the measurement of just one section, with the assumption that both sections are identical. However, that assumption is incorrect.
Buy Sophia Electric 6SN7 tubes with the best grade you can afford for years of exceptional enjoyment. Why settle for less?
