I have heard from quite a few people I trust that Kevin Deal is a great guy for expertise, quality of service and well tested NOS. I talked to him on the phone when I was searching for a new phono preamp. A real pro. Check out a great article/interview with him at www.soundstage.com and his website at www.upscaleaudio.com.
Where to buy NOS 6L6 Tubes
Where is the best place to find 6L6 NOS RCA Black plate Output tubes for my Audio Research amp. I've heard that they are the best but I really don't know for sure. I'm using Svetlana 6L6 now and would like to upgrade.
