And we have made some improvements along the way, just as ANY company does, even though the outside looks the same. We increased the amperage capacity of the IGBT modules in the PP60 in the module design after the issue wirenut experienced. Earlier models did not use IGBT modules, but rather individually soldered IGBT's. The 70 had heavier modules which could stand much more abuse. Really, they are lighter in weight now than ever, as we have been streamlining the internals but using heavier modules. Most of our circuitry has been evolving to 100% plug and play components to allow a true modular design and making long life service simple and cheap for the future
