Thanks for the feedback.
The stylus looks good on each cartridge, but don't know how to look for or evaluate wear.
As for the rubber bits, I can look for cracks, but how do you decide if there is a hardening of the rubber?
Who can analyze the condition of my old cartridge?
I have inherited a group of four older MC cartridges and would eventually like to sell them off to upgrade my own system.
I'm looking for a business or audio shop that will evaluate them for stylus wear and compliance on the rubber bits. I want to make sure I'm not selling junk. But I'm hesitant to send them to the re-tip shops, as I'm just interested in current condition.
Must be a reputable US company or shop who knows what they're looking at. No local options in West Michigan.
Seems like a lot of people would have this same need. Any suggestions?
