I'm considering buying an MC phono cartridge and would like to know if it is possible to update the MC phono stage in my CR-2020 to support 100 ohm loading for modern MC cartridges. Per the service manual, it is 10 ohms from the factory. I've been staring at the schematic and am struggling to determine which resistor(s) I would need to replace. I'm hoping someone more knowledgeable may be able to point me in the right direction. Thanks!
