Class D Amp with LM566, LM393 and 2XIRF530

[breweryfr]

Hello Mile - Apex,

With all your experiences you have on Class D and A/B amplifiers, what would be your best choice for a tri amp technology ?
Class D amp is a great deal to build, but compared with your other project (Studio Monitor Amp) I'm curious about your position on these solutions.

Anyway, your feedback will be apreciated.

Hvala za sve Diy ljubavi.....
Aleksandar.

D2000 is not tested.

 

[shehantha]

so what is the use of sharing somthing which is NOT TESTED, waste of time. once I made ba2000 it didn't work, when try to contact Mr.Mile also no use. didn't help, didn't even reply once.

I also have many pcb layouts which are not tested, so I dont share those to the people. Because I don't want to put people in trouble and wash my hands.

shehantha,
May I suggest you start your own thread and cut the inflammatory comments. To your discredit Alex has a good number of designs shared here. There is also a number of followers that appreciate his designs , efforts and support.

Hello everybody! Why amplifier can emit crackling in kakusticheskoy system? 10 Seconds playing well, and then the crackling. Power supply + - 45 volts. X-over, I turned off, crunching left.

You should rewind it. Put it in a pot with water at room temperature and boil until pieces split easily. do not force them, use gloves also.
