These also come with the Realistic Lifetime boxes.All tubes have passed shorts and leaks testing. Each side of each tube was tested for Gm (transconductance) on a recently calibrated Mercury 2000 tester. Results were:3400/3000 & 3300/3000
3300/3000 & 3400/3000
3400/3000 & 3300/3000

I paclage carefully, ship within one day, and have 100% positive feedback so you can buy with confidence. Thanks for looking!
