Hey guys,

just stumbled on this tiny power supply.

I gave this micro sized supply a  try.  I put a new end on (2.5mm) and reversed the  polarity.. so far, working like a champ.  Can't vouch that it'll work for you or even recommend it, but it's working for me. Very small and light. Isn't heating up in the least, voltage measures 9.02 VDC loaded down.

I measured a power-on surge of 425 mA for the TF, then settling down to 320-330 mA or so after it boots up. .
