Tube amp power rating question.

Is it true that the output power for the tube amp does not depend on the load? Here is the response from one maufacturer when asking about the tube amp rating on one of thier SET amp:

"Rated power of a tube amplifier remain the same at any output impedance taps unlike solid state types."

Is it true? If so does it mean I will get the same power output regardless if I use 4 or 8 ohms speakers? I thought that the lower load (i.e 4 ohm) can get more power than higher one (i.e 8 ohms.)

Any thoughts on this?

Thanks a lot,
Ake

Herman,
thanks for the info, I have two questions on this subject, the first how would you set the taps on the Tube amp if your speaker nominal impedance is 4 ohms but it can go down to 2 ohms, would you set the amp on 4 or 2? the second is how one would match the tube amp with preamp also in terms of impedance? should the values be the same or one more than the other but within a certain range? your help is much appreciated
