Sophia Electric Blue Glass 6SN7 Tubes (single)

These are out-of-stock as of 01-19-2022.  Please contact us if you would like to order these and want to know if they are back in-stock.  

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.

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.
