Guess I'll start it off.
Cross Quad Thread
The image of Eva's last topology seems to be missing, I think I may have it saved somewhere, if she doesn't mind I'll repost it in the thread later.

P.S. On a side note, we need to start building the wiki with the information from threads like the above mentioned. :smash:

Where do we most often fall short with amps?

There's some good PCB layout discussion a few pages into the thread.

Carlos's DX thread... its long now I know... but there is a dedicated site with the amp circuit, pcb etc...

It was my first solidstate amp... so it qualifies as suitable for the advanced beginner......

Awesome sound... it has only been playing since last night... but is danceing circles around my my_ref C Chipamp.

Let's not forget the Blowtorch - John Curl and friends created this.

I like ... --Susan Parker's Zero Feedback Impedance Amplifier!!!
Fifth on the all time list, and still growing; tube version split off recently, one of my (recent) favorite designs-way to go, Susan!

This thread has a nice list of amp projects here:

Water cooling class A amps.

The idea comes up every couple of months. Mainly from computer guys but I'll admit- I thought I was clever to come up with the idea too. Turns out that Grey Rollins has been there and done that. A long thread that discusses all the relevant issues of alternate cooling methods.
