  We study the action of non-Abelian T-duality in the context of N=1 geometries
with well understood field theory duals. In the conformal case this gives rise
to a new solution that contains an AdS_5 X S^2 piece. In the case of
non-conformal geometries we obtain a new background in massive IIA supergravity
that presents similar behaviour to the cascade of Seiberg dualities. Some
physical observables are discussed.
