Record Player Needle, Gartopvoiz Diamond Stylus Replacement for Turntable, LP, Phonograph(Pack of 2) by Gartopvoiz

I believe that Aiwa uses the common “ceramic cartridge” found in suitcase players, like the Victrola and Crossley. What makes the Aiwa a bit different is the tonearm functions and possibly the ability to swap out the cartridge. The styli on these ceramic cartridges are typically made of ruby or sapphire and only last about 50 hours. You can double the lifespan with something like a diamond stylus, which you can find on amazon. I don’t know if the shape should matter too much, but the styli are inexpensive, and if they don’t match, you still have an option of maybe swapping out and upgrading the cartridge to something better, like a VM95.
