Since you changed from local to octal socket, some rewiring is to be expected. The pinouts are usually quite different (i.e. location of plate, grids, cathode, filament leads). What is more important is to confer with a tube manual or online such as nj7p.org to make sure the characteristics of each tube are similar enough.

At least with an octal tube you won't have issues with poor tube pin to socket contact, as so often occurs with loctals.
