how to build tube amplifiers?

Please explain!!! I want to build a class a, small watt amp but I just don't understand any of this garble I see on the net.

I would start with a Tube Manual.
There are schematics in the back of the manual.

Class A and small watt goes hand in hand. Unless you enjoy building grossly over rated, over priced glow in the dark toys, consider the MOSFET.

MOSFETS do everything that a tube does without the pilot light.

E130L Tube Amplifier class A Single Ended (not EL34)
