For those of us who like radios that glow in the dark:

http://www.kbapps.com/tubemanual.html (the old RCA Receiving Tube Manual online)

http://www.nj7p.org/Tube4.php (good substitution data, more easily accessible than the above)

Both of these links are broken. See post #7 below for alternate sources for this data.

Sort of related to the above, here's a site that has freely downloadable PDF versions of a bunch of out-of-print tech books with expired copyrights, mostly pre-1960.

The link referenced by Carl in the first post for NJ7P's tube data has changed. His complete listing of tube data, specs, and manuals can be found here:


Tube Manual Listing from NJ7P (http://www.nj7p.org/Manuals/Tube_Manuals.php)

The RCA receiving tube manual is available here:
