I am rebuilding a pair of Rodgers Studio 2 Monitors, I understand these are rare with less than 100 made. I am looking for a crossover schematic as the values on some of the components are difficult to read. More specifically the fuzzy green things which I assume are resistors which rarely go bad but them being fuzzy tells me they are degrading and I prefer to replace them. All components in the speakers work however they sound tired and I am hoping a crossover rebuild will bring them back to life.
