Hi Tom,As your venture down the microWatt class system-matching becomes more critical than ever. Many low-ish sensitivity with huge impedance swing over it's reproduceable freq. will never work in these instances.
However, based on my experiences both 45 and 10 are really awesome-sounding tubes (providing that you have sensitive speakers with flat impedance behaviour) but unfortunately 45 is only good to 1.5Watts and 10 is about the same output level as 45.
Sonically speaking they are of different nature: 45 has a lush midrange 2 Die 4 and this is it's known strength. (very intimate human vocals rendition) It's weakness is the slightly lack of control in the bass region (designers can overcome such issue if they have the knowledge, not a big deal). On the other hand, 10 give you a more glorious, sweet sound that differs fron 45. 10 also adds a very light shade of colour along the sonic gradient background, giving you a very natural ambience effect that makes so many people lust for it. Try it with a good horn speaker system and you'll see what I mean.
These tubes demand careful design, driver circuit matching and component synergy in order to bring out the best in them.
These are just my personal thoughts. Your mileage will definitely vary...
Good luck.
