Question anyone could help me with this amplifier?

One week ago, i found on this forum a diagram of a class D amplifier, posted by "zoxx20003".the main problem is that i dont have irf540z, and i've replace those mosfets with this: STW34nb20.
When i connect them amplifier to source: +/-34v i have a big brum on the speaker, one of the mosfets heat-up more than the other, and the sound is extremly bad. i know, an osciloscope is the base of this project, but i don't have it. please, could u tell me what is wrong with the diagram, and how can i make it work?
