Class D Amp with LM566, LM393 and 2XIRF530

Зачем вы используете BD139/140? Они низкочастотные, а так же IR2110 более чем достаточно. Вы делаете это зря.

i use 2sa1020 and 2sc2655 , when using ir chip direct without a buffer , the ir2110 gets hot

thanks manoj . noted

below the measurement of this topology but in russian vvvvvv

Chingy I know is been a long time, did the power supply works well? I'm doing some cosmetic fix to the layout let me know if the PSU did work well from post #771 :)
