Excerpt from the tube collection of David Phillips. These images (tube photos) were uploaded to the respective tubes or valves by David Phillips.

This is B9A tube (without top-cap)
Ediswan, Siemens Edison Swan... GB
The 805 was not cheap to produce. Quality construction involved milling the ENTIRE anode shell form a single block of pure graphite (this is the main visible electrode in the picture). I believe this was done to make it possible to out-gas the anode by baking it at extremely high temperatures. This increased valve life.
Common type USA tube/semicond. USA
