We report here the discovery of soft X-ray emission from two highly evolved low-mass binaries using the HEAO 1 A-2 experiment. V471 Tau is a 5 x 10/sup 30/ ergs s/sup -1/ source in the Hyades with a white dwarf and K V star as components. UU Sge is a planetary nebula nucleus containing an sd0-B star and a K V-M V companion with a soft X-ray luminosity of approx.10/sup 32/ ergs s/sup -1/.
