Re: The "Sussex" Homebrew Valve Tester.
I agree with martin (G8UWM-MildMartin) regarding the use of single-side PCB, it is much easier to solder and repair those compared to double-sided.
If you try to keep all links as short as the cut pins from components those pins can be used and the spill will be less.
Also making the tracks as wide as possible without getting to close to each other will also save etching time as Ed suggested earlier. Another benefit from wider tracks is that they will work as heat reliefs for components decreasing the risk of dry-joints appearing after some time.
