Is it a hybrid (SS input / tube output?) or all tube? What's the difference between 007t and the new 007tA other than cosmetics and non-adjustable voltage to curb gray market import direct from Japan? Thanks!

It's hybrid. Only its output stage is tube based.

What are those extra 2 tubes for vs the 006t with only 2 tubes?

I'm not 100% sure. They might just be strapped together for double the voltage swing. Anyone have a schematic?

The 006t and 007t use 6CG7s, which are basically two tubes in one envelope.
