Welcome! You've certainly come to the right place, and I'll move your post to the Troubleshooting section, where you may get a response from someone at the Mothership.
The electronics do appear a bit worse for wear, but I believe in the early 80s Distillates had the electronics mounted on this type of breadboard.
As far as scratchy pots and switches are concerned, that may actually be a symptom of them not having been used much. Just do a couple of dozens of full turns with the pots, and a couple of dozens flicks of the switches, and there's a good chance they return to function normally. In any case, do not use any fluids on them, especially on the fully-sealed pots.
However, there appears to be damage to some of the wires, so it's a good idea to have a luthier service it, but Alembic electronics are a little exotic to most people (no bridge grounding, etc.) so they might get confused. Seeing you're in Nederland, I would suggest taking it to Edwin van Huik in Blaricum.
