Run out and buy yourself a copy of the RCA Tube Manual.  Yes, it's still
in print, and yes, your local RCA tube dealer (any big electronics 
distributor) will have a copy.  Or you can just think of a triode as being
some kind of big hot JFET with weird bias voltages... current goes into the
plate and out the cathode, and the amount that flows varies with the voltage
on the grid.
