I was recapping the power supply in my Emulator II and mistakenly fiddled with all four trimpots on the power supply circuit, trying to set the correct voltages. I found that only two of them affect the voltage rails (-15v/+15v/+13.2v) but the other two don't affect the voltage at all. I now have no idea how these other two trimpots (marked as R109 and R110 on the schematics) should be set and am afraid that being set wrongly I will damage the E-II. Does any of you have any idea what they do and how they should be set, or have an access to the calibration procedure of the E-II ? I could not find it in the service manual usually found on the net... here are the two trimpots as appearing on the schematics: http://www.fileden.com/files/2006/10/13/285304/E-II%20PS.JPG Thanks a lot !
