but you're right, I'll copy an existing design

I'm sure there are some well known, proven designs somewhere. I just have to find them

It looks like an update did not load right.

Don't click on the audio section. There has been some restructuring.

Click on the link "File Index" near the top of the home page.

I suppose you need more power... no?

Bricolo · 23rd June 2004, 10:44 PM

yes I found this one

I'd like more power, especially in 8 ohms

Bricolo · 24th June 2004, 09:13 AM

Is there no "DIYaudio reference design" ?

destroyer X · 24th June 2004, 09:51 AM

I did that twice, only Solid State, now trying to read all Chip amps too.

I think, you will colect all the needed informs want to have.

There's a lot of threads that will help you, put them in condition to be readed off line in the Internet Explorer ,and others too, and take notes..... i think will be very good, and will answer more than 80 percent your needs.

regards,

Carlos

Carlos,

I ofen use the search function a lot, when I need something.
Bu in some cases (like here) the limitations of the search engine prevent it from working. You can't ask for a <3 letter word, so "class d" doesn't work

or I don't know how to use it...

destroyer X · 24th June 2004, 10:28 AM

regards,

Carlos

I think UcD is looking pretty good as a front-runner DIY favorite.

Sometimes I open several pages in new windows and break my Internet connection for a while if I am trying to catch up on a thread.
