I didn't check the layout (looks OK at first glance), but here are some of my best practices for making vero layouts:
* Resistors and diodes should lie flat, which mean 0.3" lead spacing or greater (diodes can sometimes use 0.2" spacing).
* Capacitors should in general have 0.2" lead spacing (which is perfect for box or ceramic caps) or greater. An exception to this are some electrolytics which use 0.1" lead spacing.
* 0.1" lead spacing for transistors and ICc (both of which employ sockets in builds).
* Try to keep the audio input away from the power input and audio output if possible.
* Try to keep the board < 23 columns and < 20 or so rows if you want ti to fit (easily) in a 1590B.
* Be mindful of capacitor sizes! I sometimes see vero layouts with a 100uF electro next to a 47uF electro, and know immediately there will be trouble fitting things in (unless you have some of the smaller body caps). I would much rather have a larger board with greater spacing between components versus a compact layout where components are crammed together.
Finally, I always build my layouts before I post. Often I will see an error or a modification which can make the layout better, and so will update the vero before posting. And there is nothing like the feeling you get when YOUR vero fires up for the first time on your test rig! It's like turning the key on the new engine your just installed in your hot rod. Have fun!
