I'm no engineer but, transformer size, filter capacitance, output devices, rail voltage, etc. all play a huge roll in amplifier power.
You can have an amp with a larger transformer, medium capacitance, and more output devices that will "perform" the "same" as an amp with a smaller transformer, large capacitance, and medium output devices.
