Having a big transformer would mean that it has a standard linear power supply, but there is still the possiblilty that it is run in something other than class A/B. It is pretty hard to build an amp that small and dissapate the heat, especially if it's going to be stacked. There's always the possiblilty of an itty-bitty fan in there somewhere too. I had a pro amp that was 1 rack unit high at one time, but it was only 100 watts. We'll have to wait, I guess for more info.
