Hi Bert,

 many thanks.  The EEV tube is a very large circular 'squashed' glass ball with
three braided cables coming from the centre, (top),  in a straight line.
The contents inside the glass
looks like a mettalic hockey puck and is completely filled with something
orange. It has a huge circular
heat sink attached to it at least 10inches diameter and 5 inches deep of
very close finned metal - it is
a very nice tube to look at, I just don't know what it's used for.

Many thanks again

 Robin Copini.
