hi michelle,
i can see that, its small amp but the power is more than picture u post . For the hi power class D amp yes, i have it IR2110 + TL074 its scale able for its power approx 800w - 1.2 kw . the mosfet and gate resistor is important and others too like ultrafast diode, you want try to build hi-power one? if so... prepared for the hi current and protection. did u have any dc protection? if you dont, i have it with discrete part and 12vdc supply, using relay it will protect your speaker from dc output. we will start new thread for the hi power one, btw the board still small and can be bridge output to deliver more power and really need good coupling caps 1uf power supply. the quality is more than this one and more power. The original one is UCD using LM311 comparator and IR2110, but im still prefer no-ucd style using TL074 and IR2110
if u want it let me know so we can start new thread for the hi power one.
regards,
Azmi
