I've 'fixed' many malfunctioning (elderly) FM tuners by cleaning pins and/or sockets on the tubes, indeed! That said, for the OP's benefit: if you decide to go this route, remove, clean, and reinsert tubes one at a time. There are numerous carefully tuned circuits in an FM tuner; each circuit is tuned to the tube in that section. In many tuners, there are multiple 'instances' of the same tube type (e.g., 6AU6). Inadvertently 'swapping' different tubes of the same type between sockets may profoundly, and likely negatively impact performance of the tuner.
all the best,
