Its a BAD circuit, i would use a regulator chip with a pass transistor to boost the current, several available Lm317, Lm2596, LM338...
Hi, yes so I see from the feedback so far. I was hoping to avoid using regulators, ic's etc. The feature I liked the most was the red/green (ok - overload indicators) led and the reset switch. Will continue my search. Many thanks.

You can still have red/green led features with overload protection with a regulator and op amp, much more control and regulated better.
