What would you do?

For what it's worth, I picked up a Denon DP-37F a few years ago, put a new Ortofon 2M Blue cartridge in it, and have never looked back. It does have that "servotracer" tonearm, and it may be that a better cartridge would sound better in a fine but conventional arm. Still, tracking weight and anti-skate measure perfectly, and the arm tracks better than any I've ever owned. A friend has a Linn LP-12 with a Sumiko cartridge that can't track my Bob Ludwig pressing of Led Zeppelin II (which has a warp on the outer grooves). The Denon tracks it perfectly, with barely a whoosh sound for the first two revolutions. The cue is very precise and consistent, and the automatic functions, which I've always disdained, work beautifully; watching the table do its thing is like watching a mechanical ballet dancer. I've owned AR, Lenco, Gerrard, Thorens and Dual tables, all the others manual. The Denon beats them all in every way.

I replaced the cables last year, but not the caps. Never had a hiccup. And, of course, the DP-57L is a still better table. Enjoy it!

If it ain't broke, don't fix it. As long as it works properly and sounds good, there's no need to recap it. 

I'd just listen and enjoy. It will tell you if it needs attention.

I had the same situation come up a couple of years ago with a vintage Sony PS-X50 turntable. I always wanted one and found one at a reasonable price. So, do I dump some money into refreshing it or just re-cartridge it and listen for awhile and then decide? I put on the tried and true 2M Blue. Two years later I'm still loving it as is. I don't feel any need to do anything else to it (other than polish the lid,, what is this lens restorer you speak of, must look into).

+1 for just leave it alone and use it.

Recap it when something goes wrong. The caps don't amplify the sound, they just run just the arm motors and the platter. I had a Sony PS X75 and loved it, lasted forever, replaced it with a Thorens TD 126MkIII. (Now that's a lot of caps!)

A 2M Blue would be a great fit. IMHO

Enjoy, have fun with it. It's a beauty and will always be worth something to a collector.

Thanks, guys.

@tunehead ,

I'm talking about an auto headlight restoration kit.  Get a good one with a drill attachment pad. If you have deeper scratches, use a really high grit sandpaper first, then an even higher one after that, then the lens restorer. Like a 1000 grit then a 3000 grit. And of course, YouTube it!
