I own about a dozen 25-40 year old analog synths. It’s not quite as difficult as it sounds. Replacing jacks and button panels and switches and pots is straightforward soldering (it also helps that all the pads and traces are much larger and chunkier than modern gear), and anything more involved is not too expensive from various shops that specialize.

I certainly don’t recommend moving them unnecessarily or traveling/touring with them, though. They’re fragile.

Actually the really analog ones aren't that bad, they just require a lot of time. The early digital ones including stuff like a polyphonic keyboard scanner for the CS-80 are things that are really problematic.
