As above, you'll need extremely high energy amps to do the job well -- tube or ss. As noted above, you'll be easier off with a transistor than a tube -- if only considering the cost of tube watts.
Don't confuse the sonic qualities with the energy ratings -- nor the spkr ->amp interface characteristics with the electrical properties:)
There are reasons why we perceive some tube amps as being "louder" than some equivalent output SS amps -- but the "conversion" rate isn't one of them! Cheers
Is there a conversion factor for tube watts vs sold state wattsThe conversion rate is, well, 1:1, i.e. when your tube amp manufacturer quotes 50W, he/she means 50W.
