Autocostruire Kit Question

mourip · 30th January 2006, 10:16 PM

Hi,

I have a question for anyone who has assembled one of these Italian T-Amp kits...

I am completing one of these amps from a combination of instructions translated into English (very rough) and also using the photos found here:

http://www.autocostruire.it/fc/audiodigit/class-t/1.htm

I am confused by photos 4 and 5. It seems to me that the two capacitors that form the filter for the left output are reversed in the photo. The larger .33 capacitor should be swapped for the smaller .01mf. This puts the two .33mf zobel caps next to each other in between the pads for the two outputs.

Is the photo correct or am I right?

Thanks,

Paul

Paul.

Not too sure what you are saying here. The instructions I got were clear and identical to those on the website.
I just used the parts list to identify the components (c1,c2 etc...)and then used the markings on the pcb to assemble them.
I'm a relative novice at pcb work but mine worked first time.

Hi Paul, I haven't had any dealings with this Amp, but what you say seems to be right. The photo you show looks wrong..
On the front page of the pdf instructions, the caps are shown in what seems to be the correct locations..http://www.autocostruire.com/audiodigit/class-t-e.pdf

Hope this helps, Barry.

Bingo! Thanks Barry.

Now I can try the smoke test :-)
