This was left in a house I purchased and I am trying to figure out what kind of needle I need. I found some needles at a garage sale but I have no idea if they would work with my record player. How do I find this out? Thank you

Here's what I do to find needles unknown to me. I do a search on ebay, in your case use "admiral y6065" no quote and include search description. You hopefully will hit for your needle. Take the needle number and buy where you like. I stick with ebay sellers, unless a super deal is somewhere else. The main ebay sellers go to great lengths to list all known uses. It's in their interest and it sure helps the people seeking to get that old record player going again.
