Re: Lower power, high voltage tubes
Not sure I understand your post but the output power of any tube is also function of circuit design. If you want to limit current draw for the EL34s, thus output power, you can lower the screen grid voltage and increase the control grid negative bias - if you play around with long enough you will probably find a point what satisfies your needs (or you could consult the curves in a tube manual).  
OH, I am assuming that you are referring to B+ supply current - if you're talking heaters this may take more thought.
