I've thought about the current-limiting thing myself, and indeed have one I use for charging batteries, but have never known what to set it to plus I've never understood how current can be limited without cutting the voltage.
I'm trying to be philosophical about it and think that at least it's a chance to play about with alternative transistors. The current arrangement works but obviously wouldn't for long so I need to find some that can handle more power.

Edit: Thanks, Lawrence I've added the circuit to my earlier post from this afternoon. I'm not for giving up by any means - I've said before that you learn far more from your failures than your successes. I'm loath to shell out for new 'Correct' transistors as, as Mark says, the actual problem remains un-diagnosed.
