Well for a start I'd make sure its one of the analogue type, some of

And an analogue one with a poor transformer may well induce hum into the
pickup cart. ;-)

Yes, but that means it has poor regulation, which is why i wondered
whether the original was regulated. You can have psus where all that is in
the box is a transformer, right the way up to having complex regulators
inside. it really does depend on the design. This I suspect is where using
a good search engine to find technical details about the product is the
way to go here. though its unlikely to harm the unit if you get the
polarity, and voltage right, it can make the turntable work far below
par in many ways.

The problem is with early DC Pink Triangle turntables is that they were
notorious for chucking any old 9V (or in my case 12V) power supply that they
could get hold of with them. They are all different. I think they just
grabbed them from second hand scalextric sets!
