This post is very good. DIY work. Suitable for further developers. Don't use it to make it the best. But is a performance test showing the circuit that it can work As for the surachit who will take it to the top, you are not forbidden. Thank you for the kindness in sharing.: D: D

still fall in love with discreete ucd amp Mr. Kartino design :)


bad inductor reduce the stability, find t130-2 red core is better and i did mr kartino design ucd discrete and ir2110 both, btw non of them heat, mosfet or core, and core more warm than mosfet :D:D . i did test change tl071 with uA741 and both work ok. Hint.. for hi power and good class D is about cost, dont try with cheap component from china or you will be burning. i test most of the chip from china, tl071 tl 072 lm311 none of them working lol, but when i did change chip from element14 or rs-online, they work perfect. thats the different. most of people today failed to make d-amp working, because why? because first try they build d-amp with fake component cheap one, that will never success.
