There is no such thing as "tube wattage". Watts are watts. The difference is mainly in how the output is rated.Yeah, I could see that. I've always noticed that "tube wattage" seems a lot more potent than "solid-state wattage." My old "300 watt" Vetta head rig couldn't touch a 100-watt tube Marshall for sheer volume.
But remember, like I mentioned above, these could still be cabled out to the power amp or PA of your choice.
Let's say we have a Marshall Superlead rated at 100W. That's just its clean headroom. It can put out up to 180W with high total harmonic distortion when cranked. By comparison you don't want a solid-state poweramp to distort. If the Marshall would reach that 100W rating at around 4 on its volume knob, then the solid-state amp would reach it closer to 9 or 10. So that's where you get the "you need more wattage from solid-state amps" or "tube amps are much louder" thing.
Also remember settings between different amp models are not comparable and things like speaker sensitivity, number of speakers etc all matter. Use a decibel meter to compare.
