I thought it might be a good idea to share some of our most useful layouts for home-etching. It might save some time for someone else.
 
First is a regulated dual supply, based on good old lm317/337.

Second is also a regulator. It is for HV, and is the most simple version of Elvee's simple regulator , see link for components value. Btw, it works really well in one of my amps.
 
important note: since this one involves potentially lethal voltage, don't even try to use it if you can't figure out the power and voltage ratings needed for the various parts. In any case, I'm not responsible if you mess it up.

Third is a pair of small pcb (5x5 cm) to support a chassis mount ceramic noval socket. Kinda useful for prototyping.

The first two are asking for a password, the third is OK.

It should be fixed. Emphasis on "should".
 
Here's a fourth. It's a very simple low power amp based on the tda2616. Not a great amp but quite useful when a few watts are needed. It's very similar to the Velleman k4003, except I added an rfi filter and redid a bit the layout. All values according to the datasheet.
