The max base-emitter voltage of the driver transistor is 0.65V without a load on the project and 0.8V with a 100W load.
the max base-emitter voltage of the output transistor is 0.7V without a load and 1V with a 100w load.
The two voltages are in series so the outputs of the LM358 are limited to 1.35V to 1.8V.
If the transistors are good and are connected properly then 13V at the output of the opamps is impossible.
You must have the wrong transistors or have their pins connected wrong.
