Schematic software

So what software is available for schematic and parts layout, that is used by you folks. I used to use Claris Draw, but it's not on my Windows XP laptop. (IBM T40). I'd like freeware of course. I have Open Office Draw, but would like to find something that has libraries for electronics. Suggestions??

BTW I do some tube layout, SE amps mostly, as well as OPAMP preamp and headphone amp stuff.
I have TubePad, but it's just .bmp cut and paste.

Thanks

Hi Sparky,

Here is a link to a list of links to lots of design-automation software. Some is free. Most have free functional demos.

For PCB layout, I use (and love) Easy-PC, from Number One Systems ( http://www.numberone.com ). It also does schematics. But I almost always use LTspice (free from http://www.linear.com ) for schematics and simulations.

Also, I _highly_ recommend sending every new pcb's Gerber files through the FreeDFM utility, at http://www.4pcb.com (the Advanced Circuits website). It's a really-great tool. Besides the manufacturability checks, etc, that it reports about, you also get high-resolution PDFs of each layer. (I actually use those to create the user documentation for kit construction, etc.) Also, make sure that in the price-quote section of what you get back, you try increasing the quantity desired, and see how (little) it changes the total cost. The price per pcb can be _extremely_ low, for larger quantities. Their pcbs are absolutely fantastic, too. And it's definitely the most-painless way I've found, to get pcbs made commercially.

I just noticed that Advanced Circuits now also has free PCB-layout software, but haven't tried it, yet.

I've also been happy using Easy-PC for schematic/layout and Advanced Circuits for PCB production. I haven't tried AC's FreeDFM or PCB layout package. Instead, I've used Easy-PC's Gerber import feature to verify output. This costs extra, so FreeDFM might be the better way for a new user to go.
