You are correct. The Plate CCS was an early original upgrade. As the schematic shows a JFET input, the next upgrade was a MOSFET front end with the small SMD current source to bias the MOSFET. There was also a small power transformer board mounted next to the original choke to provide the negative voltage. The original Power Supply was redesigned with the needed output winding and the extra transformer was deleted in subsequent revisions. The pic was my Rev2 board (circa 2008) with all the subsequent upgrades. It was recently sold, so I did not have the documentation to refer to. Thanks for posting the link.
