Questions about tubes and gear that glows. FAQ

I just installed a new SET integrated amp and upgraded the preamp tubes to a pair of NOS Mullard 4004. It's been a LONG time since I had tubes. How long does it take to break in the preamp tubes? The rest of the tube complement has about 200 hours on it.
