"The unit appears to be working reasonably well as I did some basic testing. However I noticed the pitch sometimes seem slightly unstable, and also I wasn't too sure if Ring Modulator 2 is working as how its supposed to since the sound seem out of tune when VCO II is set on Ring Modulator 2. The unit is missing VCF H.P. switch as shown, you can still control using your finger or a pen, however I couldn't really tell if both VCF L.P. and H.P. switches are making any changes to the sound its producing.

Otherwise, everything else appears to be working fine to the best of my knowledge, there is a bit of noise on some of the knobs and sliders, which should do with some servicing/adjustment too..."
