Brent Jesse is the man! I needed a quad of tubes within .5 db of each other for my Thor 3000 phono stage. This was my first replacement since the preamp was new and the manufacturer is out of business. He found me some really nice NOS tubes that just put my phono side over the top in musicality. Besides being a serious tube guru, he is a true gentleman. He understood that although I wanted to try some NOS tubes, I really do not want to become a tube roller - I just wanted my preamp to sound good.
Highly recommended
