NOS does not always equal good in tubes. EVEN when new there were always a good percentage of tubes that were factory duds, and THAT was ~40+ years ago!...Tubes ain't like milk, but they are not exactly like wine either. Age just marginally increases the chance of pulling a dud from a batch of NOS tubes. If you are curious find a local (radio/TV/audio) collector with a working tube tester and see how that NOS replacement tests...I'll betcha a cookie it is either weak or leaky/shorted.

Oh yeah! Sorry - I didn't say that... I did put the back on after changing tubes... =)
I have a place I am trying to get to in a neighboring city that has a tube tester. I plan to check them both!
