Seem to have forgot my name agaiin on the last 2 posts of mine...

Drifting a little but SRS, I presume you can get an equivilant to the "multi-output" DC power supplies we have in the UK? I've a regulated one that is switchable between 1.5V and 12V DC, can supply up to 1A at 12V and has a range of adaptors/fittings which depending on which way they are connected sets the polarity. I've found it quite handy either for powering something I would normaly run on batteries or to try to power something not working.

(here) is similar (same make but a later model)
