Being able to draw and read a load line is the key to all of this tube stuff. If you can take a date sheet and plot one. You can design an amplifer.

It's not hard and dosen't require a lot of math. If I can do it anyone can (Everytime I start a project I have to hit the books and refresh my memory)

There is an excellent article at http://boozhoundlabs.com/howto/
He walks through the whole design of a 6v6 amp. The first few pages are a great into to load lines and op points. Read it a cople of times till you can draw your own, say at 200V or for a 3k load.

There will be a quiz tomorrow, so everyone bring a #2 pencil to class...John

as one of my Mechanics Prof's told me something like, "Pen on tests is motivating".

But with load lines, many copies of the plate curves and pencil is a far easier method.
