Abstract
An attempt is made to trace back the possible progenitor systems of the Algol-type binaries TU Mon, SX Cas, and DM Per. The present characteristics are compared to the result of the evolution of 9M 0+5.4M 0. The position of the hot components in the HRD is discussed with regard to the theoretical models.
