I recently finished this 4-channel Amp built with two Class D Audio IRS 2x250 modules (they can be bridged to make a 2 x 500W amp, or a 3-channel 2x250, 1x500). I included a relay for 12V triggering by my receiver. The case is a Hammond 2U aluminum one (with my screws). I built this for use as a sub amp, but it sounds very nice with my Abbeys, driven from my receiver preamp.

Here are my small amps modules - a prototypes to a further project - nearly as small as big stamp so I called them StampAmp The modules are based on MPS chip MP7782. Starting them for the first time I was really surprised - the small guys sound really amazing driving my 4 Ohm ELAC 207.2 with JET tweeter.

VERY SMALL! looks like a nice clean layout too, whats the power ?

[ChUmI]

The chips are rated according datasheet at 50W with 10% THD+N what means definitely clipping in my understanding. I've got exactly the results, see the screen shots below. Continuous power of 40W without any heat sink for 1min - with small heat sink for 15min on 6R on the first screen shot. On the second 50W with clipping - is it 10% ??? hard to say Playing really loud music below clipping level you do not any heat sink!

Very neat and tidy - I like!

It's been snowing today so I've been busy wacking together a little project. Actually,I am finishing up an Arjen Helder TA2020 T-amp and power supply combo that I started on last weekend. It is still breaking in so the caps are still a little shrill but just today it is starting to smooth out to the point I don't miss my ST-70 with the VTA mod so much.

Pardon the Cuban cigar box. I found it at Goodwill for a dollar (and I'm sticking to that story). The power supply box is an old project box which came in a box full of old 1940's and 50's toy train parts that I have used some of the switches and lights from too.The copper accents are from the back plate of a gutted Akai M-8 reel to reel that was converted into monoblocks last year.

Happy Holidays and enjoy the Snow!
