We study an AdS5 solution constructed using non-Abelian T-duality, acting on the Klebanov-Witten background. We show that this is dual to a linear quiver with two tails of gauge groups of increasing rank. The field theory dynamics arises from a D4-NS5-NS5' brane set-up, generalizing the constructions discussed by Bah and Bobev, which realize N=1 quiver gauge theories built out of N=1 and N=2 vector multiplets flowing to interacting fixed points in the infrared. The central charges computed both holographically and using a-maximization are shown to agree. Our result exhibits $n^3$ scaling with the number of five-branes, suggesting an eleven-dimensional interpretation in terms of M5-branes. \\ \\Based on 1705.09661.
