My hobby has for some reason devolved into a sort of analog-Indiana-Jones adventure where I scour the earth for old cartridges and health or NOS stylus assemblies, Beyond the interest in actually setting up the carts, I thoroughly enjoy the research and unearthing these goodies from wherever they hide (often mislabeled or vaguely labeled Ebay listings...though I'm not too good to consider myself above sniping a well-watched properly labeled listening).That is why, with mechanical components especially, I prefer new. I don't need to inherit someone else's headaches when all I want to do is play records. It's such a gamble. A cool older TT could never give me a single problem, or it could be an endless string of issues that keep me from using it. Which, ironically, was the problem with the prior new turntable I bought! 🤣
Going down this rabbit hole of carts took off when I really settled on what turntables I run. And of course the ONLY one not fully functional at the moment is a late 1970s complicated direct drive linear tracker. The rest of my tables drive a platter with a belt attached to a simple reliable motor. There's not a lot to go wrong, and I made sure to buy healthy examples. My Strathclyde, for example, came from the son of the original owner and I have the original receipts from the late '70s from a long-gone store in Chicago's suburbs. Actually, now that I think of it, I have the original receipt for the complicated DD, but a lot of good that does with the rats nest of pulleys and electronics that's under the plinth in that thing.
Anyway, the point is... old does not necessarily mean headaches. Some old stuff is decidedly simple.
