Description

Here we have a beautiful quad of 8417 Sylvania Audio Power tubes up for auction. They all appear NOS, but no factory boxes. Each tube has been completely tested for shorts, and Transconductance on my Hickok 539C tube tester. Each tube is numbered with a label on the guide-post of each tube. These tubes are closely matched. All tubes are US made. #1 Gm: 13,000 #2 Gm: 12,500 #3 Gm: 12,500 #4 Gm: 14,000 Tubes will ship in a white, tube-box with the tube number written on each box. They will be carefully packed. Check my feedback since 1998. Thanks for looking. Good luck.
