This Korg 800DV Duophonic Analog Synthesizer came in with the usual issues when you have an old lady like this one. Cosmectic condition was great, but inside are these old electrolytic capacitor that needed to be changed because they do leak physically and will damage your synthesizer over time. Switches, sliders and keyboard needed a little cleaning.
There are lethal voltage exposed in electronic devices. Unless you know what you are doing, don’t try this. If you following along, you doing so at your own risk. Bring it to a qualified tech. Bring it to me.
I’m documenting repairs for my reference and yours.
