Monday thru Wed. We took the time to replace all of the AA/AI chassis with chassis that had the TI chip replaced with an AD8622 or AD8672.  In the end we had hoped to have all boards installed with AD8622 but have a number with the AD8672.  The only technical difference we care about is the amount of current the 8672 draws as it is higher than AD8622.  We will have chassis that run a little warmer than others.  The entire site has been changed out now.  This would not have been possible to accomplish in this time without the help of Steve Vass and Bob Taylor who came up to assist.  Thank you.
