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.

Translation:

Why are you using the BD139 / 140? They are low-frequency, and the IR2110 is more than enough. You are doing it in vain.

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 🙂

For +- 56V, lytics should be rated at 70V. Or 56WV.
