  We study a model in which the electroweak symmetry is dynamically broken by
technicolor interactions and the symmetry-breaking is communicated to the
quarks and leptons by a weak doublet of scalar fields. The scalars may be
regarded as elementary or as light bound states arising from strong extended
technicolor interactions. This model is unusual in that it can provide a heavy
top quark without generating large flavor-changing neutral currents. Our work
focuses on the model's phenomenology, particularly the oblique electroweak
radiative corrections. We demonstrate that while oblique corrections and FCNC
effects limit the allowed parameter space, the model remains viable. In
particular, if the scalar is relatively heavy, the model can accommodate a wide
range of top quark masses.
