My understanding of "I would remove the rear 4 12AT7s (you need some of them in place, even though you are not using them)." is " remove the rear four 12AT7, AND (leave the first 2 12AT7 and rear number 7 CCS 12AT7 in place, probably due to Phono/linestgae unit configuration).

I checked line stage MP3 specs online, there are only two 12AU7 and two 6SN7.

Re-read this quote: "you need some of them in place, even though you are not using them". there seems no need to use any NOS tube!
