Sophia Electric™ Premium 6SN7 Input/Driver Tubes
This new blue glass 6SN7 has rich tonality and big sound stage. Designed to compliment to Aqua 274B and Classic 300B tubes, the new 6SN7 is a great choice to replace vintage 6SN7 tubes in all tube pre-amplifiers and tube amplifiers.Note: The original 6SN7 has been discontinued.
6SN7, like all dual triode tube, has two sections. To match the two sections closely enough is hard enough; matching two tubes--four sections--would be much harder if high standard of matching method is applied.
Note: Some internet vendors would only test one section of the tube due to the limitation of their vintage tube tester (like popular TV-7). So those claimed to be matched may be matched by one section only, with assumption that the two sections would be identical. However, that assumption is false one.
