Looking for a reliable 100w design

rockgardenlove · 11th February 2009, 02:41 AM

Hi,
I'm looking for a reliable 100 watt design. I really want something previously tested out, if possible.
100 watts isn't really too hard a limit, I just want it to be able to go pretty loud.

Any ideas? Thanks!

Do you want only schematic or plugandplay tested module

How loud is really loud and how much power you need is mostly a matter of your speakers

Krill - The little amp that might...

If you want tested modules take a look at aussieamplifiers

This is the FA1.. still blasting away for 4 months...
A more refined version is here....

Fa1 and 3 both working in the house, very common,standard
topologies. Zip files have BOM,PCB,Schema, and LT - complete.
If you want MOSFET "power amp under development" is
what you search for , but I have those amps , too...

NMOS 200 /350 .pdf's are the ones..

For that kind of power, Nmos200 will be a nice choice, small component count, easy calibration process, small footprint (~4"x3.2"), common parts... I loved it.
