This new blue glass 6SL7 has rich tonality and big sound stage.  This new 6SL7 is a great choice to replace vintage 6SL7 tube in all tube pre-amplifiers and tube amplifiers.

6SL7, 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.

Buy Sophia Electric 6SL7 tubes with the best grade you can afford because it will provide years of enjoyment. Why settle for less?

User Experience:

Just got them installed...using your Blue glass tubes in input...6SL7 and 6SN7....My Audio Mirror SET 45 watt amps sound better than ever... The 6SL7’s replaced some Sylvania VT229’s which are very good but yours are even better...thanks.
