This is probably a dumb question but.... I assume all of the pictures in the tube reference on this site are looking at the tube fom the bottom, correct?

True that! No question is dumb, though. I hate it when people get angry at me for asking questions or for not knowing about something. Anyone who tells you something about "common sense" is a moron. Common sense as they call it is acquired. You don't get it until someone else gives it to you either by example or by explanation.

Cheers!

I think that it's conventional to show the physical wiring and pinouts of tube sockets as viewed from the bottom, with pins numbered, from 1 to whatever, clockwise. Normally, repairmen would be looking at tube sockets from beneath the chassis.

Some octals, for example, have only 7 pins. The pins are numbered counting the position where the missing pin would have been.
