Ok, so the tube just arrived, everything seems just fine, but i havent got
the time to fire it yet. The thing is i have noticed a really strange thing
- there is an extra cathode wich is *upside down* number eight in the
middle, in between two and five. It looks like its not connected to any
It appears to have a few hours on it, although it should be an easy task to
remove any oxide buildup (cathode poisoning) from the digits.
They're scarce these days, so handle with care :)
Regards, Jeff

Yea i know you can fix cathode poisoning quite easily, but whats with that

I have several with similar darkening, and they are just fine. But, like
Jeff says, it most likely has a few hours on it. It may be fine and then
again, it may not! No way to tell until you get your hands on it. I can
tell you this, most of the 5680's I have that have this sort of darkening
