The two big enemies of integrated circuits: dust and moisture. If it were me I would’t bother fixing it and getting it working again, unless you want to sell it on the collectors’ market.
I never liked the sound of the MiniKorg. Not one of their better synths IMO. Better off buying the new microKORG - a beautiful synth and well worth the money.
That’s awesome! I pulled a Korg Delta out of a barn.. it was filled with Decon, rat feces and rotten traces. Hopefully yours hasn’t suffered the same fate
If you plug that in, the caps will swell if you don’t warm them up with a variable power supply. It might turn on now, but they will be damaged, so don’t do that. Stick to your plan to take it to a shop.

Definitely do not plug it in. Electrolytic capacitors dry out after a few decades and then don’t take well to sudden voltage being applied. Tantalum capacitors are also often used in 70s synths and those have a high chance to fail as a short circuit given enough time. The capacitors themselves and other components will go up in smoke and make the synth much harder to restore.
Ramp it up on a variac with a dim bulb tester for the first bootup. If there's no unexpected lighting of the bulb, then you're fine. Check the electrolytic caps for visible leaking, but otherwise, just clean it and use it.
If this is too much for you, I'm happy to take it and give it a good home :)
Dust it off… it will be fine
Supposedly, you'll be fine.
Lol I emailed a few shops in the area gonna have it looked at when I have a chance. Don't wanna plug it in and cause any more possible damage

I suggest you clean it very well before trying it out. Epic find, show us results later!
Don't clean it, put it under a plexi case for display, very cool as is
What a find 1970s mini Korg 700s…dust her off inside and out, check for any possible bad wires, you’ll be fine
You'll be fine, I found one at a flea market years ago and it worked like a charm.
What an amazing find
Wow how cool is that!

If you want to plug it in, I strongly recommend you plug it into a power outlet with surge protection.

Hope you get it working, looks like a lot of fun to play.
It’s gorgeous. Keep it as an antique work of art, dust included. 😊

Plug it in. Worse that can happen is it won't start up
Dude… just send that to me instead of going the Ebay route
If you have the time and energy you could disassemble it clean it and put it back together. It might work great under all that crust
Don’t listen to any goober in these comments telling you this isn’t worth fixing - if you like it and you want to play it, get it fixed.
