EverythingPCB is a good starting point to look for software for free schematic/pcb and related software:
* PCB Layout / Design / Schematic Capture / Autorouting Software
* Demo, Shareware, Freeware & Trial Offer Software
* Design for Fabrication / PCB Design Validation
* EDA Simulation & Related Software
* Electromagnetic Simulation
* Gerber Editors / Viewers, Data Conversion & Translation Software
* Signal Integrity / EMC, EMI & EM-Modeling Software

A comprehensive list of EDA software and Tools.

For libraries read this:

Basicly IPC-7351, IPC-7352 if you follow these guidlines you wont go wrong.

There appears to be a large valves (tube) library available on this site:

Using free pcb software can be a false economy.

You cant beat pcbcad with good comprehensive error checking.
Nothing worse than getting pcbs made and there are mistakes on them.

Thumbs up pcb

I think the eagle pcb is better because it is' simple and intuitive.
you can draw directly to the board and use a large library of electronic components, without converting the electrical design.
if you use a CNC prototype, and eagles' much better.

+1 for DesignSpark that was briefly mentioned earlier. I was a bit hesitant at first but having just completed a 1500+ part mixer I can honestly say that its got 100% of what you need and 99% of what you'd like. As for libraries, I always create my own 'cause third party ones although generally accurate don't share a common style and can look scruffy when mixed.
Also check out 'Free LP Viewer' from Mentor, and 'PCB Design Tutorial'</b>RevA.pdf

Altium is great - I love it. But it is not free. Far from it.
Nice work, BTW. Looks great.

All of the proffesional packages will do the job, I use Cadstar #1, then Allegro when I have to, but are a expensive option for hobby use (We pay nearly £8K maintenance just on EDA software).
The problem is to find a free or reasonably priced package that will cater for DIYers going into digital designs, as with the decent free packages you have limited pins and layers, which can be a big limitation in digital design. I have had a play with a couple of the free packages (Eagle and the RS offering and found them OK).
