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.

Baldin · 4th July 2010, 07:54 AM

What is LM2104?

savu · 4th July 2010, 08:14 AM

Maybe an opamp.
I am sure that it is a spelling error

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
