I have noticed a few adds lately as I have been shopping for some tubes like yours that a seller or two has mentioned in the add that the tube had the same issue as you have with yours and that it was not an issue with its performance. I did pass on these, so don't know if there was an issue or not and appreciated knowing the fact before hand.
Tubes sound like a broken lightbulb
So I just bought some pretty fancy NOS tubes from a big online store. I unpacked them and notice they sound like a broken lightbulb 💡 when I handle them. Is this normal? I paid a lot for these tubes Because they were promised to be and test as brand new.
the tubes are Slyvania Jan-chs 6sN7gt / VT-231 2 rivet “bad boy” tubes
thanks for the feedback
