I have an LED driver here with an output of 72V, unfortunately it has an unknown IC so I've no datasheet to see how the voltage is set.Presumably its a matter of changing a couple of resistors? Any pointers on where to start?

Any pointers on where to start?i salvaged led light from dumbster (similar size as long flourescent tube). the chip driver is WS3441A offline non isolated led driver. its constant current driver instead of constant voltage. so i guess you put anything on the output, it will produce any voltage necessary to get the set constant current... the chip number is barely visible in the picture you posted, maybe you can clean some more and look the number under microscope, ymmv.
