"I'm thinking of converting my phase inverter tubes from 12AU7 to your 12AT7, since I already have some NOS JAN 12AT7s in stock."
I will be very surprised if this produces any audible or measurable improvement regarding distortion. The LTP is inherently "linearized" due to internal feedback, just like a cathode follower. My last amp used a 6J6 LTP and managed < .035% THD at 5W output. Curves for the 6J6 clearly don't support this level of performance.
