Is it specifically a Univox K2 or a MiniKORG 700s? Does it have only two sliders for the effects section (a basic level/tone setup), or three (a more intricate level/course tone/fine tone)?
Mine is a Univox K2 with only two sliders for effects. The sides were painted, mostly clean on the front panel. Definitely needs some repair work, but it'll be singing sweetly by August
Univox K2 with three sliders.
Turned it on for a minute here at work. Sounds old. Not clean but everything seems to work. Pretty happy considering how (relatively) little I paid for it. The upside is that there won't be any particular diagnostic work to get it going. Just have to clean it up. Then detune 2 OSC. Then add MIDI and ext in to the filter. I'll be recapping at least the power supply too.
I love how odd these guys are...and of course the filter.
Never before have I loved a square osc tone on an analog synth. I always wanted PWM or saw. Lately I've only been doing square tones on my 700s. It has a quality that sounds so melancholy and romantic, like it should be "THE" tone behind every pretty synth pop song.
Also I have discovered ring mod sweeps through long delay, and it makes me feel like a scientist making lazer guns.
