I just realized I left out a couple steps if anyone cares.

I started with a single pair of KenRad VT-231s in V1a--sound better than the Chinese 6AS7GTA in V1a.

I installed 3 Sylvania VT-231s into V1b, V1c, and V2 and a Sylvania 6SN7GTB in V4. Better sound yet. Listened for a couple weeks. Life was good.

Heard short ~1 second static burst in one channel. Tapped on the VT-231s and the pair in V2 were microphonic although they were dead silent and sounded good (when there was no static burst). Used that as an excuse to try out the 5692s, so one pair at a time I swapped 5692s for VT-231s.

None of these changes were earth-shattering. The burn in process was the biggest change, followed by swapping in NOS 6SN7s for the Chinese stock tubes. The difference between VT-231s and 5692 and 6SN7GTs is much subtler--I can be happy with either.
