The whole tube layout thing has me confused: P/P, Tri, Set and such in regards to output when when a person speaks in watts.
I have a restored Scott 200 (12W) in a second rig.  I'm looking to switch from SS to tube (Zen Integrated) in my main rig.  I realize the Scott and the Zen Int.  are different animals,  but from a general yardstick comparison (output),  how do they compare ?

Thank you in advance for your reply,  David
