    On my B&K 675 tester Tube 2 = 2625gm and 2600. Tube 1 = 2500 and 2500. These are superb gm measures for an Ebay tube offering and were very close to what was described. Packaging was also superb! The best shipping packaging for tubes I have ever seen. And given the quality and military spec of these tubes only the best packaging was required. This is a highly respected and notable seller on Ebay. My thanks and highest recommendation! What a great VALUE!!
