Item History & Price

Information:
Reference Number: Avaluer:4807814Modified Item: No
Brand: National UnionCountry/Region of Manufacture: United States
Original Description:
Here are 4 National Union made early 50's 6SN7GT black glass twin triodes that I have tested on my TT-1 Mutual Conductance tester. The Philco has a base crack. The minimum for a good 6SN7 tube on this tester is 1680. These tubes test: 2400/2400,  2150/2300,  1700/1500(the Crosley) and 2000/2000. I guarantee 3 of these tubes are useable. I will attach readings, and can combine shipping with your other winning bids.
