I’ve had very few problems with electrolytics in the many TRS-80s I’ve worked on. It seems to be one of the places where Tandy did not cheap out. There are some tantalum capacitors to be found in TRS-80s. These have a tendency to fail to short so I am wary of them but still, I would probably not replace any unless they failed.
