From monitoring, with the benefit of relatively nearby SDRs (Argentina--unfortunately there are no Peruvian ones), there seem to be only 4 Peruvian tropical band stations left (4775, 4810, 4820, 4955) with a possible fifth on 4830 although I may be the only person who thinks so! But according to the Peruvian government, as of 2021 there were 47, plus another 19 on 49m and higher (what they call "onda corta internacional" as opposed to "onda corta tropical."

Unfortunately I haven't found a straight-through listing of these mostly dormant if not imaginary stations, but you can look them up department by department at
https://rnf.mtc.gob.pe/Radiodifusion. Some of them don't have a razón social (d/b/a name), just some guy's name, and it's not clear if they ever went from authorization to operation, but they have call signs. Interestingly, there's a Peruvian shortwave band plan by departments, which would have been useful back when there were a couple of hundred such stations, but hardly necessary nowadays.
Addendum- Some stations that seem to have abandoned shortwave still list the frequencies on their web pages, such as R Huanta 2000 (4755) and R Quillabamba (5025).
