I am building the amp with the PCB's of Digi01 and can't find the capacitor (Cin) from 4,7 mu with a distance of the legs from 5 mm of 10 mm. All what i can find is far too big.

Does anyone know were to get is???

Thanks a lot.
 
Hi Wim

If you look at Zangs picture his cap is raised. I don't know if the board was designed to have the cap sit on the PCB.

I just rx'ed a new set of boards from Zang and they have pads for surface mount components.... I may go that route..

Hi kzar and all,
the 3886igc boards are not available now.I am planing to make a updated version.

any recommand input are welcomed.

Zang

none that i can see ... still tring to figure out why mine arent working... i might buy some new lm3886s to see if the ones i got by chance were bad...everthing else on the boards are correctly installed checked them over 3 time before soldering and 3more times afterwards... only thing left is the IC.

Steve @ Apex . jr sells them cheap. Where are you in TX? Email direct with answer.. stgrab@yahoo.com

I have some of these boards still unassembled, and we can build / photograph each step and component used.

I have a few of the first boards, very nice indeed. The only suggestion I would make would be to move the chip a little further toward the edge of the board. I found that I had to grind off the edge of the board in order to mount it flush to a heatsink.

/Dave ... still a loooong way from that 6 ch amp I decided to build in 2004.
