Hello all
Sorry if this question is a bit obscure, I am really hoping someone can help.
I am using an a old legacy system running MIDI to analogue multitrack.
I have an XRI XR300 MTC striper, the original white one. It uses a plug in 9V power supply. I lost the original adaptor so I do not know whether the polarity is centre negative or positive. There is no polarity information on the back or in the instruction manual.
I dont want to risk plugging in an adaptor with the wrong polarity in case I fry a chip.
Most units have a protection diode I know but I dont want to take the chance.
Can anyone help please?
Thanks, Smithers
