These internal pics show the 2 amp boards are actually quite small, the rest of the case is full of the transformer,power and output capacitors and heatsink for the transistors. they're only 45W per channel (into an 8 Ohm load)

The 2 amp boards are the square ones.
one advantage of this award winning design is the fact they are unconditionally stable under any load and are able to even stand a direct short or open circuit (no load) without damage. They don't even have output fuses
Plenty of room for a nice bit of modding!
