From: "phix_it" Date: Mon Mar 10, 2003 8:36 pm Subject: Ring-Mod Schematic error Hello Ken, (and all) I just took a peak at the 1973 Ring Mod Schematic in the Files section and noticed an error. The 33K resistor attached to pin 3 of the LM307 shouldn't go to ground but rather to the junction between the right side of the X input Capacitor (100n) and the ajoining 68K resistor. As it's connected right now you merely have a VCA circuit. Just thought I should bring it up in case anyone tried building the thing and found it didn't "Ring". That's all for now..... Dean. --------------------------------------------------------------------- Message 131 From: Date: Tue Mar 11, 2003 6:29 pm Subject: Re: [resergence] Ring-Mod Schematic error > I just took a peak at the 1973 Ring Mod Schematic in > the Files section and noticed an error.

Actually I don't think the 33K should be there at all. There should be a link between pin 3 and the 100n/68K junction. The 33K should be present in the VCA but is deleted in the RM.

That will teach me to adapt one piece of artwork to another. The corrected version has been uploaded. Ken
