As I think I mentioned, my 550 is switchable for "MM" and "MC" levels of gain. There is a toggle on the front panel. In MC mode, the input signal goes to a JFET which just adds gain and then feeds the aforementioned RIAA circuit, which is all tubes. In MM mode, there is a relay that shunts the JFET to ground, thus bypassing it. Does the 650 also have provision for MC cartridges, using JFETs, or have we been over this ground, already?
