The DFP power supply says:
24v 750mA positive tip
and the DFGT one says:
24v 0.7A Positive tip
(750mA = 0.7A)
So they should work
About the DFP power supply, the plug did fall off but i used my ace soldering skills and heat shrinking skills to solder it back on, it is a solid soldering job, i can pull it pretty hard and the wires do not pull of. i cannot remember what it said on the multimetre but i can check for you.
The solder job is on the low voltage side of the transformer so there is no shoddy mains connection, i might get some pics up at some point if you are further interested.
