<FONT COLOR="#0000FF"><FONT SIZE="2"><FONT FACE="Arial">This rules out misadjusted balance trimpots on the VCA's. I don't think there's a trimmer that will solve this problem. Just tossing it around in my head I am thinking that there may be a ground connection that's opened up. Probably the first thing I'll do is get the scope out and probe all of the pins along the bottom of the VCF/VCA card, ac coupled, high gain, to see where the signal is coming from. I'll let you know what I find!!<BR>

Sounds like dried out power supply bypass electrolytics. This would be after the voltage regulators. If the bypassing is bad the oscillators will appear everywhere through the power supply rails.<BR>
