Obviously you can skip one relay. If you skip relay REL2 you can also skip D2,T2,R3,R4. If you skip relay REL1 you can skip D1,T1,R1,R2

@anticimex I can see where that is a good thing

@nekitoss Hi! Thanks for you input. CUrrently I do not have any plans to change anything on this board. Its created in Eagles CAD which i havent used since i moved to Kicad. I dont even have it installed anymore. The good thing is that all files are included so you can download and change for yourself.

@JahFyahh - I still haven't managed to et round to it. I've been really busy since this project and its still hectic here. I'm sure i read a few reviews somewhere, here or google. Not sure.
