The Tech 21 Leeds does the LAL tone perfectly, unsurprisingly! A P bass helps, but it nails the Hiwatt drive. I use it with a Thunderbird too. It's been my preamp for a few years now.
Don't pay too much attention to the Tech 21 clip though as it misses the point entirely.
As for the post-Moon albums, I think they are very good in places. Just not great Who albums, if that makes sense. Both are covered in Entwistle's monster Alembic, both 4 and 8 string, and are worth hearing for the tone and playing if nothing else - both feature some of his finest studio work.
