We describe how unbounded three-form fluxes can lead to families of AdS(3) x S-7 vacua, with constant dilaton profiles, in the USp(32) model with "brane supersymmetry breaking" and in the U(32) 0'B model, if their (projective-)disk dilaton tadpoles are taken into account. We also describe how, in the SO(16) X SO(16) heterotic model, if the torus vacuum energy Lambda is taken into account, unbounded seven-form fluxes can support similar AdS(7) x S-3 vacua, while unbounded three-form fluxes, when combined with internal gauge fields, can support AdS(3) x S-7 vacua, which continue to be available even if Lambda is neglected. In addition, special gauge field fluxes can support, in the SO(16) x SO(16) heterotic model, a set of AdS(n) x S10-n vacua, for all n = 2, .., 8. String loop and a alpha ' corrections appear under control when large form fluxes are allowed.
