It's amazing how long-lived 70s era technology really is. We can only hope that its knowledge is preserved for future generations.
For comparison, the electronics of the ancient AO-07 amateur radio satellite from 1974 is still working, despite that hard radiation.
Main reason why the sateliite failed at one point in its life was that its main power source was failing:
The AO-07 had NiCD batteries had caused a short, so the whole system was inoperable.
Once the batteries became an open-circuit, the solar panels were able to bring the venerable satellite back to life.
Unfortunately, the Voyager twins rely on RTGs with Plut.-238 (PuO2), which has a lifetime of 87,7 years,
but the efficiency of 6.5% of the old RTGs and the high power consumption of the sondes both lead to a much shorter lifetime in reality.
