yyz, you probably already know this, but unless you go out of the way to find a high maintenance tube preamplifier, there is no comparing the low maintenance cost and requirements of a tube preamp to that of a tube amp. My tube preamp takes four small preamp tubes, two for the line state and two for the built in phono stage.
There is no biasing, you just plug in the tubes and you are done. Inevitably you will want to try a few different brand tubes to flavor your sound to you liking. But again, its basically plug in the tubes and you are good to go for years. It may be what you are looking for.
