You can use a class A circuit at higher voltages but you'll have to choose the current with taste.
Be careful how you say things here Peranders! You may find yourself being sued for damages with remarks like that to a complete newbie!

What I ment was that sometimes you actually must design, not only choose more is better.

DIY is a mixed bag.
1.) Those that copy a good established design and obtain success.
2.) Those that can interpret a design and redesign to match their purpose/circumstances.
3.) Those that are eejits that think they can alter things without a basic grounding in arithmetic.

Far too many fall into this last category without ever realising they should be in category 1.
One must be numbers savvy if one is ever going to progress past category 1. There are no exceptions.

Default A second look

Hint:

Next time you send away your gerber files, use a separate gerber viewer. By that you can much more easily catch errors, like in your case the component print.
I use Viewmate from http://www.pentalogix.com/ freeware.

With a real gerber viewer you can see how the pcb will look like, exactly.
