This is a Rectify Series drop-in speaker system for Atlas Classic & early-run Master SD-35 locomotives. The speaker is a beautiful press-fit between the rear weight and motor mount. No frame/weight/shell modifications are needed! The factory PCB will need to be removed with a hardwire decoder installation.


The speaker comes fully assembled and tested.
