  "abstract": "We recently presented a new $D=5$ $\\mathcal{N}=8$ gauged supergravity involving the local trombone scaling symmetry. It arises by consistent truncation of M-theory on the internal space of the Maldacena-Núñez AdS$_5$ solution dual to the $\\mathcal{N}=2$ four-dimensional superconformal field theory (SCFT) of class $\\mathcal{S}$ associated to M5-branes wrapped on an unpunctured Riemann surface. Using exceptional generalised geometry/field theory, we extend that construction to show that the same $D=5$ $\\mathcal{N}=8$ supergravity also arises by consistent truncation of $D=11$ supergravity on the family of $\\mathcal{N}=1$ M5-brane-wrapped solutions of Bah-Beem-Bobev-Wecht, including the $\\mathcal{N}=1$ Maldacena-Núñez (MN1) configuration. Then, using recently derived mass matrices, we compute universal sectors of the Kaluza-Klein spectrum on the MN1 solution. In general, this universal spectrum is only locally defined, and we give a prescription for extracting globally defined subsectors thereof. This globally defined universal Kaluza-Klein spectrum is dual to a universal sector of the light operator spectrum of the SU(2)-flavoured $\\mathcal{N}=1$ class $\\mathcal{S}$ SCFT dual to MN1.",
