H again.
Ok, I am glad you found what you needed.
But just for the record, here is my idea.
You will have to read my earlier post to get an idea of how I think it should work.
If you use bigger transistors (higher power) then you can use more current. Ofcourse the big trade off is the power used by R1.
I don't know if it IS needed, and may not actually be needed.
