Simple lm3875

RightOFMind · 23rd February 2004, 08:43 AM

I'm a newbie; this is my first electronic project. I've been looking at tackling this projecthere

The part list describes an MKS4CAP 4.7uF 100v. I can't find this anywhere for sale. Maybe it's not listed right or I can use an alternative.

Like I said, I'm very new at this and this is mostly a learning experience...using the LM3875's, I'd eventually like to create a nice 7 speaker setup to plug into my Audigy2 (PC Sound Card / for 7.1, I've already got the subwoofer taken care of)

Please help me with that capacitor and any advice people can give for this configuration x 7 would be greatly appriciated!!!

You dont need a 100V cap on an input, in fact if your source DC is =< 3mv you dont need the cap at all.

You say that you are a newbie so do yourself a big favour and build a simple stereo amp first.

When you have that working properly, you will be in a good position to build a seven channel version.

But of course, emphases on "eventually"
