if you are facing the front on the preamp, the line stage looks as follows:
12AU7. 12AT7
12AU7. 12AT7
the top row corresponds to the left channel and the bottom row to the right channel
in the older model of the ultimate, 12AX7s were used instead of 12AU7s in the line stage but the order is still the same.
hope this helps
