Just to tag onto the comment from Tre a bit, when you put a choke in you now have two things to consider - the DCR (DC resistance, which is very small - not sure, but probably a few hundred ohms tops) and the reactance - think of it as AC resistance, which is very large as Tre points out. So a choke makes a nice low DC presence on the grid of the 300b, but a very high AC presence, also a good thing.
