1 Western Electric 276A metal base power triode 100 watt audio tube. The tube looks very clean and I doubt it was used much if at all. It is similar to the rca 211 and frequently replaced 211d 211e. The plate max voltage is 1250v and filament 10v at 3a.
I used 10 volts on the filament and you can see picture of it lite up. I cannot test beyond this and will only guarantee that it has a good filament.
