While I don’t have your experience, I have heard from others who have
extensive recapping experience, that over time, electrolytic capacitors in
equipment that is not used can degrade. To prevent degradation, the
recommendation is to use the equipment for 30mins a year to keep it
exercised.

If the equipment hasn’t been used for an extended period of time then
exercising the equipment may not result in satisfactory function.
