The main purpose is to say: "You have been warned, so anything you do is 
in your own responsibility."

Right, its knowing which places you can safely touch and which you better 
not touch. THere are books on electrical safety, mainly with respect to 
mains wireing, but these are good guidelines. Keep as much insulated, so 
that there is little chance that you accidentaly touch anything.

I for one never work on high voltage circuits when I'm tired or distracted. 
Being concentrated and knowing what you do are my best advice.

I can only say how I started: I build my own PSUs. What you can learn there 
is proper insulating, fusing and grounding. 

>Also, what type of power supply would you use w/ a tube based design? 

Mine is a 2x30V transformer that I run into a voltage doubler circuit, yields 
about 140V. Doug has also a PSU design on his site. 

Cheers,
 René
