I would not bother replacing anything:
First off: Measure the temperature rise of the heatsink for the FET's, the
transformer (and any other component running hot) at rated load. This may
require several hours for the temperature to stabilise!
Next: Add a fan to blow air through the unit, heatsink & transformer should
be in the airflow. Measure again. Increase the load (very) gradually until
the temperature rise after several hours is the same as what you had without
Measure the load -> this is what you can eek out of the unit with forced
cooling. It will not be possible to improve this without major surgery -
especially to the transformer.
There may be overcurrent trips, fuses and other stuff preventing you from
increasing the power. It is also dangerous - there is high voltage, heat
sinks may not be insulated etc. You know what you are doing rite?
