@MsMadLemon This sounds like what I discovered with my parents’ modern record player (a Crosley) when I tested a couple of vinyls I got from antique traders in Rhode Island. Even if it was fully switched to the built-in speakers, there was this tinny sound which also played the same track. It felt odd.
I’m thinking more and more that a refurbished deck is the way to go! I’ll keep you posted! 🫡😃
