IMO sell it and keep your Denon especially if it is functioning fine.
These SL-1200 knock offs are plagued with problems - from inability to hold constant speed, loose tonearm bearings and I actually seen one where the paint was flaking off the strobe dots. But the worst part is the entry level built-in preamp. If you bypass it to use your own, it will introduce noise into your system. I have heard many accounts of folks stuck with this TT asking for advice on how to remove it.
You bought it cheap so you should be able to get your money back.
