In this work we revisit the problem of studying spin-2 fluctuations around a class of solutions in massive type IIA that is given by a warped AdS3 × S2 × T4 × Iρ and with N=(4,0) supersymmetry. We were able to identify a class of fluctuations, which is known as the ``minimal universal class'' that is independent of the background data and saturates the bound on the mass related to the field theory unitarity bound. These operators have conformal dimension Δ= 2(ℓ+1), with ℓ being the quantum number of the angular momentum on the S2. We also computed the normalisation of the 2-point function of stress-energy tensors from the effective 3-dimensional graviton action. We comment on the relation of our results to the related AdS3 and AdS2 solutions in massive type IIA and type IIB theories respectively.
