[GreenKeys] WESTERN ELECTRIC VACUUM TUBES

[Steve Cichorsky]

I would like to thank Sam Hallas for optimizing the scan of the Western 
Electric Tube catalogue in order to make it easier read and to use.

It was very nice of him to take the time enhance it for the benefit of 
others.

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
