If you want the set to be reliable, then by all means replace the electrolytics on both the sweep board (the top one) and the signal board (the lower one). I have one of the same model and it recently lost the picture and I suspect the trouble is a bad cap in the horizontal section. Transistor radios of the same age are coming up needing all electrolytics replaced. This TV should benefit greatly from a recap.
