NOS AS7s in MA-1s?

OTL Asylum

OTL, Output Transformerless Amplifier User Group.

This last retubing I put NOS AS7s in the front four positions of my M60s. I saw this recommended somewhere, and I like the look. I can't tell any sonic differences, but the GE JAN NOS tubes supposedly have a little more power than the Sinos.

Does it make sense to use the GE JAN NOS tubes in the MA-1s? If so, should I run all 28 the same, or mix/match with Sino tubes? If mix/match, which locations should the NOS tubes go in?
