I bought it with a Denon DP5f tt and Denon SUT. All in the early '80s when I was an air traffic controller, single, and had disposable income. No such income now.

I've recently pulled it out of mothballs. I'm looking at the cart., at the end of the stylus, there is at best a miniscule bump. Using a magnifying glass, I can see it's a crystal element, but still just a bump.
I have no idea how much time I put on the stylus before putting it away in 2002 on moving from CT to PA.
Meanwhile, I had to replace the dl-301 once in the past, while waiting on it's replacement I bought a Shure V 15 Type IV MM cart. This has little use. Using same magnifying glass, I can plainly see long, thin crystal projecting downward from the stylus.
Shouldn't the DL-301 diamond look the same? Do MC diamonds start out smaller than MM diamonds?
I'm confused, and need advice as to what to do.
