Where else do evangelicals get their truth?

Through the holy spirit for one.

And how, exactly, do individuals ascertain that their assumptions about the Holy Spirit's guidance are, in fact, correct? Every wind of doctrine claims inspiration from, or direct institution by, the Holy Spirit, yet they are very often mutually exclusive. Who decides which, if any, are truly led by the Holy Spirit, and which are derived from...other sources?

In any event, Catholics consider Sacred Tradition to be the work of the Holy Spirit, and therefore on a par with Scripture, yet it is rejected across the board within Protestantism as being "extra-Biblical." How is our version of the "work of the Holy Spirit" inoperative and ipso facto rejected, while far more novel doctrines, mutually exclusive as noted previously, are given a free pass as "the work of the Holy Spirit"?

Hmmmm.... Evangelicals involved with extra-biblical revelation? Are you sure about that?
