In response to Rdavwhitaker's query, if you're using a really low output MC cartridge, you might be better off with a decent quality solid state phono preamp, as there will, "typically", be less of a noise floor than with a tube preamp. (That is one reason why I prefer having a solid state preamp, and having tubes in my amp.) My Dynavector XV-1S cartridge, (0.3 MV output), has no issues whatsoever with my solid state preamp.
Another two cents from me.
