Radiotron Designers Handbook (4th edition)

The 1952 Radiotron Designers Handbook (4th edition, "The fat red book") is considered the authority for tube buffs and designers. The following is, as far as I know, complete. If there are omissions, please let me know or send them to me so I can add it here.
This would not be possible without the efforts of Tim Williams and Choky, so a big round of applause to them :-)
The book is in PDF format, so you'll need Xpdf (many platforms) or Acrobat Reader (many platforms).
Please do not try to "hack and leech" the files at a faster rate, as I'll permanently remove them from this site. Thanks.

PLEASE: Right/Long-click and "Save As..." for future reference.
Evenings and weekends (eastern US time) are best for this mirror.
