This is an honesty issue.
Always hold them from the ends. On all of them I have an outside regulated dc power supply that feeds the tube tester correct heater voltage .
This offer is for one tube. Vintage tube testers almost always, due to age, have very low heater voltage s.
I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. The voltage needs to be 6. I don't guarantee or imply anything else.
I will not sell a tube that feel last or has been abused. I will bend over backwards to make sure that you are a happy customer.
