I'm trying to make the broth part of Maanchi's tteokbokki recipe and it calls for dried anchovies. I'm on a bit of a time crunch so getting them online isn't the best and the closest Asian market is hours away. Could fresh Anchovies replace the dried ones? 
Speaking as someone who has made this broth, it will not work.  Fresh anchovies will add too much oil and will break up in the broth, making it cloudy and too fishy.  You really want to look at other dried ingredients. The answers to this question cover a fair range of what those dried ingredients could be.
