I'm trying to do this with the least risk to components.
Clamp the FETs to the heatsink and while it's drawing excess current, twist, push, pull on the transformers to see if that makes a difference in current draw. This may work if the supply doesn't shut down.

I’ve load the drive circuit (103J) and the drive circuit is ok, I guess I’m having a faulty transformer, what’s your take Sir Babin? With the rectifiers out, all that’s left now is the transformers.
That's why I suggested that you twist, push, pull the transformer to see if the current draw would drop.
If you have shorted diodes and output transistors the transformer is effectively shorted causing the drivers to heat up.
If the amp is working, you can use 2 IRFZ44 and the power supply will work for low power levels and testing.
