Was not a bad tt when new. Hard to tell what the arm is from the picture, could be a Fidelity Research, could be an arm made by FR for Luxman. You could always do better with a newer cart. I don't recall if it is belt drive or direct drive, I presume the latter, if I am mistaken, a new belt is always a good idea. Getting parts such as the missing strobe light is not the easiest thing in the world. There are concerns specializing in turntable repairs and some in vintage equipment that could be of help, but unless you find that this table has value as a collectible, I would use it as is until I can afford a new or newer table. There are many new models out now at reasonable prices, most if not all equipped with an OEM Rega arm (250 or 300), that, coupled with a new cartridge, would provide, in all likelihood, better sound.
Good luck.
