All three are 12AY7s.

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?
Yes, but I will tell you again. THere are JFETs that switch in and out from a front panel switch...just like yours I think. I found that even with a high output MM that the MC input sounds better.
(1) I apologize. You did clearly tell about the JFETs before I asked my stupid question about whether it can handle MC cartridges.
(2) You don't mean to tell me that you use the MC inputs for MM and other high output cartridges, do you? Most likely that would result in dramatic overload of the RIAA circuit. I must be mistaking your intended meaning.
