I have 2 Mullard 12AX7's and 2 Mullard 12AT7's to replace the stock tubes in the line stage portion of my C2200. I don't use the phono section..yet. In its configuration, the are V1-V8with 4 for the line stage and 4 for the phono. Which 4 tubes are for the line stage portion? The manual does not indicate. Thank you very much. Dave
Truth is this is not really a tub pre. Look at a schematic it's almost unbelievable. A technician friend who services Mac were talking about the pre when it came out & we looked at the schematic there it was. O yea this thing is loaded with 30yo IC's (not good).
