Those were simpler machines than the current ones.
And perhaps many of those broken parts can be machined on the cheap.
It's not rocket science really.
Computer power supplies that use group regulation and don't have synchronous rectification can generally be repaired indefinitely.
There are no complex transformers (used in resonant topologies) and only fairly simple semiconductors are used.
Mostly just replace the capacitors showing wear and you should be good to go for many years.
Semiconductors don't fail as often, provided they are not overly stressed by design (running close to their limits).
But if they do, you are better off with older designs that use common components and not PITA to find and replace chinese or american IC's.
Some random chinese chip could have been made by a small company that is now defunct.
American chips are just plain expensive and often hard to obtain. Good quality and excellent performance though.
