How would you go about spraying solvent in a sealed pot anyhow?

Caps of higher tolerances (10% or better) are best sourced from Mouser or Digikey here in the US. Look at the temperature rating also, especially on caps in the PSU. 85 degrees is standard, 105 degrees is higher quality and longer life.

8000 Hz: spot on! I'll have a look at that keyboard circuit and share whatever I learn. I used isopropyl alcohol to clean the bus bar a while back and haven't had any triggering issues, deoxit is the plague imho.

Rebuilding the power supply got my Sonic Six up and running, but there's always been a low level high pitched noise on the output. It's not effected by the filter or amplifier and it's steady in pitch but the amplitude varies some.

This video shows the same problem on someone else's Sonic V:
