Want to make sure we are comparing peppers to peppers as we assess the quality of the repaired PEM STS2 and attemp to understand the problems of the original STS2.  I also moved it to the exact spot where the oriinal was located.  If things still look so-so by Monday, our net step is to place the STS2 on the concrete.  STS2-B has always been sitting on the floor vinyl wereas STS2s A & B are on the concrete.
