Hi, I am still having trouble with this VCA design: https://drive.google.com/open?id=0B2yaoNYlV1nMWFhSRWUwdlU3TzQ It is noisy, and it gets worse as you turn up the gain. I tried switching to a 2164 design but its no longer available in SMT. Any ides? -- --Tim Ressel Circuit Abbey timr at circuitabbey.com
