Steve,
I had nothing better to do this morning. I have got the necessary 
software so I did the conversion to B&W. The converted file is at:
http://www.samhallas.co.uk/greenkeys/western_electric_tubes.pdf
and it's only 2 MB now with bookmarks.

Notice that the handwritten page numbers don't match the actual ones. I 
tried to make them fit but gave up when the characteristics charts 
stopped matching the tube type somewhere in the 40s
Cheers,
Sam
