Comment: The difference between 302 and 303 models is the size of the speaker and cabinet style. Otherwise, both models share the same chassis and schematic.

It also appears that Models 302 and 303 are identical in appearance and operation to models 332 and 334 respectively.  The listing in the service manual does not explain the difference(s) between the model pairs. Model 302 also shares the same cabinet as model 291.

302/303 schematic is here.
