Recently removed from storage David Hafler components that I built in the late '70s and early '80s. Basically, a DH-200, DH-101 and a DH-300. They have been boxed for about 10 years. I'm not a student of electronics, more of an enthusiast and constructor. In the process of updating the DH-200 and recently discovered DCV at the outputs that I didn't realize existed. R39 resistors are okay and will probably replace the input pairs and see what happens to the offset. Hope to gain much needed knowledge here on the forum. Thanks.
