startup massive oscillation. normally you would swap the OT blue and brown wires as it seems to be a 50/50 proposition. In my case i'd rather not do that due to wire length. can i instead swap the grid wires (the ones with the stoppers). will this accomplish the same thing?

yes
Maybe next time don't trim the OT primary leads until the NFB phase is verified correct.
