Just out of interest, does a TG16 use the same leads as a Core Grafx/II?
I know the pad is different, but are the power lead & av cable the same?
No. The TG16 only puts out RF, without an adaptor; the core grafx is set up for A/V. I don't know what the core grafx requires for power, but I'm pretty sure it's different from the TG16.
I use a 9V AC adaptor for mine.
