    A couple of good reference sites

    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.

    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
