hi guys ! there is a better comparator than LM311 pin compatible? i found LM106 but in romania no store have it
Hi All,
Refer to the original schematic if my supply rail is +-70V ,what should R7 be ? I use 470 ohm .Is it correct?

That looks like a fake IR2110 
You can see in the IR2110 datasheet, on the last page, how the markings should look.

hi khron
greetings exactly what i suspected ic pins were repolished
thanks a lot
thanking you

Looks fine to me, I got 3 or 4 that are pretty much the same
And they look something like that
PS: No most of them are like that
PS2: 2 of them are like on the picture, 3 of them are totaly 100% like he has, and two of them are in smps and Damp now and working
An externally hosted image should be here but it was not working when we last tested it.

hello friends! At once,Sorry for my English please! I'm from Ukraine😉
I want to make this amplifier and the first questions is: Is this scheme worker?
In the last my amplifier was lm311+lm2104+bc 807+IRFB52N15D,conservatively of course.

hi d class diyers
greetings any voltage test points voltage on ic pins will be very
helpful output has 69 volts dc any hints
thanking you

Hi everyone..
After long time I came to the forum and searched for a class D amp. I saw this thread in an accident and luckily. I have never tried a class D amp so far because of the complexity.. I'm really amazed by the design and really glad to hear that it works..
I dont care THD values and any other comparison of this with other amplifiers. because if you care of those, you better try there are many appreciated amps here. But I enjoy the simplicity, output power and the efficiency with this. I'll be really happy if I could get powered my woofers with this 🙂)
My plan is to drive a subwoofer from this with a low pass filter. mid and highs form another amp.
Thank you all for running this thread with helpful stuff.. Pro engineers please look at this and tweak it with the minimum complexity. your work will be appreciated. because DIY should to be simple otherwise it has to be "do it by others".. lol.. just a joke 😛 🙂)
regards,
Lycanlk
