The MKS80 generates so much heat internally that even though the capacitors are rated at 105c (instead of 85c like the JP8), they still fail eariler than many other vintage analogs.
If your MKS80 ever breaks and produces a huge wash of white noise, no matter what the patch, the cause is most likely failed electrolytic caps.
If recapping is chosen, it should be noted that one capacitor on the rev 5 voice boards (C119) should be installed backwards from the board's silkscreen.
Roland goofed there. Verify before removal and replacement.
Also, the heat can cause the trimmer adjustments to crack.
Here are some photos of a late model (rev 5) MKS80 with almost all trimmers cracked:
