Gorgeous Denon DP-1200 Turntable Service

Rollin’, rollin’, rollin’..! Join me once again as we look at one of my favourite turntables, the gorgeous Denon DP-1200 direct drive.

A quick recap for those who don’t know: Liquid Audio began as a turntable specialist when there was a maximum of just one other turntable specialist in Perth, and few in the entire country. This remains true, though many others have since claimed to do this work. That business owner (my good friend) and I used to chat about setting up the businesses we run today, and even what they might be called, and we remain friends and colleagues to this day.

In contrast to my colleague, I began slowly as my business was only part-time while I still taught science and worked at Curtin University, with small numbers of everything from regular to high-end turntables like the Kenwood L-07D, Luxman PD-444 and PD-555 and gorgeous, killer tonearms like the SME 3009 series 3, SME IV, Audio Technica AT-1100 and Dynavector DV-505. That was nearly 15 years ago! Wow, how time flies.

My first entire year of posts was about turntables-only; check out my sitemap for those and others, and my apologies for how they’ve aged. I’ve repaired and written about many other types of equipment over the years, of course, and developed additional foci on amplifiers, CD players, Accuphase, Krell and Sansui, for example, and which I enjoy very much, but the focus on turntables never diminished, only grew some company!

With that in mind, let’s next look at another of my all-time favourite turntables, the Denon DP-1200 🙂

Denon DP-1200

Background

Regulars may recall articles I’ve written about the venerable Denon DP-1200 over the years, including one about resolving DP-1200 speed issues and one about DP-1200 motor service. This is no surprise as the Denon DP-1200 is both a relatively common model and one of my favourites in this mid-tier of turntables from the golden era. I’ve been lucky to have serviced and repaired dozens of these over the years.

The DP-1200 is a relatively feature-rich direct drive turntable with a good tonearm and thankfully without any features that would otherwise detract from its performance, like the unhelpful servo arms of later Denon machines. There’s a strobe to confirm any of the speed weirdness that indicates the need for service, as was the case with this unit. There’s also a lovely arm lift and lower mechanism operated by a large switch, and an auto arm lift at the end of a record, operated by a smooth solenoid and damped cam and lever mechanism.

Denon DP-1200
The Denon DP-1200, as she came to me, from a long-term returning customer. Note the classic Denon ‘UFO’ styling, which I rather like and common to Denon turntables from this era.

Speed feedback is provided by Denon’s standard magnetic strip method. Whilst not quartz-locked like the Kenwood KD-600/650, it is locked to the AC mains frequency, which is remarkably stable long term. Short-term variations are integrated out via the control circuitry and feedback mechanism itself, so you end up with excellent speed accuracy.

When you see the engineering and construction quality here and compare it with what was available elsewhere in the turntable world at the time, you realise just how hokey some other ‘highly regarded’ designs really are. This was often driven by snobbery and ethnocentric thinking that values creations from some parts of the world more highly than others, based on nothing other than a feeling of superiority.

This is truly as stupid as it sounds, and many of you, especially Japanese and North American readers, will know just what I’m talking about. You know, the “Oh, but it’s from Japan, so it can’t be any good.” I refer to it as the great British hi-fi press ‘ruse’ of the 80s and 90s, which saw some ordinary equipment gain far higher market penetration than it should have. Paradoxically, the reverse was in fact true: equipment like this Denon DP-1200 is so good because it was from Japan.

I prefer to rate equipment based on its engineering, technical and sonic merits and then assign superiority where applicable. This way, one only has to deal with facts and observations based on hands-on experience – ie what matters. We can ignore magazines filled with mostly paid opinions written by reviewers who peed in the pockets of manufacturers who advertised in their magazines and let them keep the equipment they reviewed.

You won’t find any advertisements here, of course. But I digress… For another great and underrated Denon turntable from the golden era, check out my video about the beautiful Denon DP-3000 / DP-3500 I repaired a year or two ago:

Another Denon UFO..! What a beautiful turntable. Let me know if you’d like to read more about this one and if not, I’ll probably write about it anyway 😉

Service

This Denon DP-1200 came to me in need of the usual TLC, due to a lack of service and maintenance over the years. The cartridge and tone arm were poorly set up, leading to diminished sonic performance. The deck was experiencing speed fluctuations and a few other long-neglected lubrication and adjustment issues needed attention.

This is typical of DP-1200s, I see, most turntables for that matter, so it’s not a judgment of this owner by any means, just a reflection of what often happens with equipment like this. Anyway, without any further ado, let’s go!

Denon DP-1200
As always, I start with a cleaning of all visible surfaces and then continue by disassembling the deck. In this case, that means removing the platter, extremely carefully, due to the very fine clearance between the platter’s magnetic strip and the tape head speed sensor.
Denon DP-1200
We then move onto the underside of the deck. Here, I’m going to do a bit of cleaning and lubrication, focusing on switches, controls, deck master speed adjustment and the mechanical arm lift/lower gubbins, to the left. Note the beautiful motor of the DP-1200, a seriously overbuilt affair. We can access the spindle bearing through the bearing cap. Note also the transformer, suspended by rubber vibration absorbers.

Observers may also note the chassis construction favoured by Denon here – particle board, like the Sansui XR-Q7 I recently wrote about, and in contrast to the metal used by Technics with the SL-1200 and the ARCB composite favoured by Kenwood for the KD-500/550/600/650, amongst others.
Denon DP-1200
One frequently neglected aspect of service on the Denon DP-1200 are the combined arm lift/lower solenoid, cam and cam rest/damper. You’ll see that the rubber part is degraded and fit for the bin only. I’d not serviced this deck before, so it remains, until now…

And here, I’ve installed a nice new damper rubber. I’ve also cleaned and lubricated the pivot points of the mechanism to facilitate smoother operation and longer life. Everything, including this tiny rubber part, matters, believe it or not.
Denon DP-1200
That includes this pivot, as well as the switch clearances, all of which should be checked and adjusted, as required.

With those mechanical aspects of service completed, the next important and again often neglected aspect is to adjust the deck master running speed and 33/45 RPM synchronisation. I love my wooden blocks for this, as they don’t harm turntable finishes and leave me with clearance to get in and under a deck like the DP-1200. Good balance is important, though!

The last step with this Denon DP-1200 service is to remove and clean the cartridge, stylus, and check fastener tightness, overhang and then reinstall and adjust azimuth, tracking force, anti-skate and VTA.

The Audio Technica AT-13ea is a classic moving magnet cartridge, fitted to an equally classic AT D-7 headshell. They still work well, but they are ancient, and a deck like the DP-1200 really deserves something better than an ancient, worn and basic MM cartridge. That said, nice alloy body on the AT-13ea, really cool.

One option is a new JICO stylus, at around $150. A better option, though, is a new and better cartridge that retains genuine stylus availability for the next decade or more, a concept the owner and I discussed. I typically recommend, supply and fit cartridges in the $700 – 1500 AUD price range for DP-1200s. She will be back for a better cartridge at some point.

Denon DP-1200
Here, those adjustments have been made, and the correct overhang is now set. This was the largest set-up issue, being almost literally ‘miles’ out!

Results

I think anyone would agree, properly maintaining turntables like this beautiful Denon DP-1200 is an absolute no-brainer. Not only are they now highly collectible, but they sound great when properly set up and replacing one is not an easy task.

Is the current Technics SL-1210GR a fair comparison? Yes, I think it is, and if you want one, definitely speak with Dan @ Addicted to Audio (Perth) and tell him I sent you, but having worked on a few of these modern direct drive machines, honestly – I prefer the DP-1200. Horses for courses, I guess, and your views may differ.

Denon DP-1200
Oh, what a beauty, and in good company next to my pristine Kenwood R-5000!
Denon DP-1200
You may note how much cleaner she looks now, with decades of environmental dust and dirt removed.

Either way, the owner is very pleased with the results of this service and totally appreciates how good this DP-1200 is and how lucky he is to own one. Now THAT is a customer I respect!

Denon DP-1200
What a stunningly beautiful design, don’t you think?

  1. Great article, I love the UFO styling as well. One downside I’ve read about these Denon turntables is that, if the magnetic strip (to keep speed accurate) is damaged, it’s nigh on impossible to find a replacement. Is this a fair concern or not really a problem?
