I spent the better part of a summer in the 70's on a contacts welding project in my area, we had 39 central offices that were largely the same level of hardware. It was cheaper to clean off the old worn contact material and reweld (electrically) then remove and replace many of the wirespring relays in use. Not to mention, if I did my job right, a lot quicker then the R and R process if that relay had suffered a total failure. -- Paul Holmgren Mine: 2 57 300-C's in Indy Hers: 05 PT GT R/T HO Stage 1 Hoosier Corps L#6 ************************************************************* To unsubscribe or set your subscription options, please go to http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1
