Need help on Nuarc 26-1k part, pic included
I have suckage with the Nuarc, which is good, but I am getting no lamp. Started looking though the pieces and noticed that on the LC 13 starter board there was a blackened vacuum tube that looked questionable. I fiddled with the fuses, etc, press power and pop! There it goes. I was wondering if anyone can help identify the component? It looks like a really easy solder.
Here's a pic of it still connected to the power board:
