“I had a preamp built for me and it came with Sylvania NOS chrome dome tubes. Had an issue with one of them as it delaminated on the bottom plate. The builder sent me another one and the sound improved, but still not what I was looking for. When I installed the 6SN7's, the sound immediately balanced out even though I had not burned them in yet. Looking forward to see how they mature over the next 200 hours of use. Will be ordering from Kevin again, very responsive and nicely packaged.”

“This pair sounds great in my Cary SLP-88 which needed a refreshed pair after about 26,000 hours.”
