SGFX uses the PAD-113
DC 9V 800mA
Center plug negative.
TG16 uses..
DC 10.5V 730mA
Center plug negative.
as long the plug fits it should work, altough in a slight risky condition, since the voltage is higher (-> will produce a bit more heat at the internal 7805) and the amperage is slightly to low (in the specification only), I dont think the SGFX sucks fully 800mA.
please also confirm the TG16 specs with yours, since I have those information from the internet and never saw one in person.
