Oberheim OB-8 Analog Synthesizer - Problem


YouTube Published on Aug 18, 2012 by scott2eh

"Old analog synthesizers develop a lot of problems as they get older. I had a VCO chip go in my Yamaha CS-40m this summer and a similar problem in my OB-8. This is a demonstration of the problem. We swapped the VCO chips and they seem to be fine. I also went through all the calibrations and they were all fine as well. Because this varies widely with room temperature I suspected a capacitor but it doesn't seem to be that either. At this point, it's still a mystery!"
