Apparently you want a power amplifier that can drive a speaker, not just an amplifier.
link has one I found, there are many others.
This one just uses one tube http://www.lh-electric.net/projects/tiny... If you use a semiconductor HT rectifier I suggest you fit a switch to the HT output and mark it up "Standby/ON" so you allow the tubes to heat up on Standby before you apply the HT. You get better results soundwise if you use a half wave tube rectifier instead.
Here is a link to a decent paper on designing a single ended vacuum tube amp.

I am halfway through my electrician class and after christmas we are going to build induvidual projects by our self.
I know how a transistor amplifier work and how to build one. But i want to make a tube amplifier.
where can i get a simple circuit of a guitar tube amp with few components. like 1-5W
