I got my sister pregnant once. Yeah, that was awkward, but mostly because she's 6 years younger than me.

Yeah, it uses half of one as a power tube. It's British-voiced, good for classic rock up to some harder rock. It lacks bottom-end, so buy your speakers accordingly if you're looking to get it. It's a nice bedroom amp, also gets louder than you'd think, especially through an efficient speaker

I don't think you can compare the tubes, there are too many other factors.
