For consideration is my collection of vintage 6SN7 tubes. All tubes were NOS and used sporadically to moderately in my former Eddie Current Super 7 and Eddie Current Balancing Act amps. The pairs may not be exactly matched after use because the ECBA only required one, so I tried to rotate on occasion to use them evenly, but I don’t have a tube tester to measure these. I do know that they all work and sound excellent. I’m only selling because I no longer have an amp that uses these tubes.
