I am wondering if my circuit is really the same as yours because I have only 3 tubes in the whole circuit (not counting the power supply of course). If the Input for each channel is SRPP then that would be 2 out of 3 tubes used already. The last tube, I am assuming after the RIAA network, would have to serve both channels and could not be a second SRPP + cathode follower, which would require at least 2 more tubes than my phonostage has (2 tubes more for the second SRPP one per channel). I suspected that my input was SRPP then the network and then I thought either a CF out but I didn't think that would be enough gain or a plate loaded common cathode (but then the output Z would be high) for additional gain.
Mine also has the JFET inputs for MC, which I use even with MM and it sounds better that way.
