What stock tubes did your MG Head OTL come with? They seem to vary, but mine came with Sovtek EL84/6BQ5s and a Ei (Yugo) ECC83 (the same as a 12AX7).
I'm using JJ EL84s (don't bother with the Sovteks) and have tried a variety of 5751 tubes for the driver, and the Ei ECC83 has crisp highs, to the point where the vintage tubes seem rolled off by comparison. But the Ei wasn't as sweet in the midrange. My current favorite is a Raytheon black plate 5751. I wonder how it compares to the 12AU7 you're using--I might have to grab one to try out.
