Is my Denon DP-51f toast?

Postby thoutah » 19 Jul 2017 17:52

So, for the past 15 years or so, my main turntable has been a Denon DP-51f, which has performed flawlessly until this week, when it began doing just about the worst thing a turntable can do to one's LPs.

Last night while listening to a record, about midway through the side, the needle abruptly started skating outward over the grooves. Naturally, I leaped off the sofa, bolted across the room, and lifted the tonearm. I attempted to set the needle down at the beginning of a track, but it started skating outward again. I put the tonearm back in its rest, but I noticed that it was hovering over the rest, rather than sitting in it.

That seems to indicate that the tracking force just stopped working. I pressed the lift button twice to raise and lower the arm, and that re-engaged the weight, and the arm then sat in its rest. So, it seems okay for now, but who knows when this could happen again?

So, I've seen threads here with people who seem to be fairly knowledgeable about these Denons. Does this sound repairable? Or is it time to move on?

Unfortunately, my trusted local audio shop doesn't do repairs anymore (they only fix the used stuff that they sell), so I'm not even sure where I'd take this thing. But more importantly, my understanding is that the inner workings of these Denons are fairly complex (sensors and whatnot), and they could be tricky to repair, and parts could be difficult to find.

I'd appreciate any thoughts or advice on this!

This sounds like a failing capacitor issue. After so many years a recap is probably the right way to go. And yes, it will likely happen again and over time will happen more frequently as the capacitor health continues to worsen

Try calling George Meyer AV shop: they seem to know what they're doing, quite knowledgeable when it comes to Denon turntables. They may be able to diagnose over the phone or have you send them the unit.

To me it seems that nobody actually knows what's causing this strange behavior, but because it's a pretty old turntable people like to say it needs a recap.

I've had the same problem and I also don't know what the problem is, but I haven't used my DP-51F for a couple of years and now it seems to work fine after I fixed another problem.

Recapping may or may not be necessary, but I sure am no expert on that matter.

I posted a reply in this thread as well as it was the first I read: odd tracking? tonearm force? problem with DP 52F

See the DP-52F topic in this forum.
