first time build set trimpot to minimum, if you dont hear any sound at output, then slowly increasing the trimpot, it will be set duty cycle for this amp, too high will make mosfet overheat, too slow it will not oscillate. if there is anything or problem please ask me and make ur amp work and running nicely.
