preamp with phono break in


I purchased a new tube preamp(Doge) with the phono section and would like to know the best way to accumulate 100 hours for break in. My only source is a tt with a mm cartridge.
thanks

Albert, thanks for the info, one more question, how high does the volume have to be?
why the impatience? I never heard of buying a piece of gear and needing another piece to break it in..the new market for people who need their fix quickly?
I don't think it is impatience as much as it is how you deal with listening to music that is not produced in a manner pleasing to the ear. Isn't that why we invest all thin $$?
to hear Sweet music. I really like my system to disappear and I haven't had that for a while. Happy holidays to all
