Plinth ideas for DENON PD-80 DD turntable
While my pair of Victor TT-101 still sleeping in the storage, i decided to buy another Flying Saucer.
The DENON DP-80, vintageknob always have nice images and info about rare stuff...
On that page you see DP-80 with DA-401 tonearm for hich compliance cartridges (i have this tonesm NOS). It could be an interesting project, it was hard to resist ...
The question is the Plinth for this Denon DP-80.
The original DK-300 plinth is an option, but searching for something better i found this one.
Custom made plinth is always an option and i have superb Audio-Technica AT-616 pneumatic insulators to use under the plinth.
But what do you guys using with your Denon PD-80 ?
P.S. some companies now producing even an iron cast plinth and graphite plinth, i have no access to graphite, but iron cast here is cheap to make a custom plinth.

Genesis, The Motor in the DP75 is considerably smaller in the DP75 and the control system simpler, both are excellent machines. The DP75 and DP80 are not suitable for use with a copper mat as the platters are two layer spring loaded the weight of the copper cause the springs to sag too much. The DP7000 is also a magnificent table - have made many of these into GrooveMaster Vintage Direct DP7 https://pbnaudio.com/pbn-dp7/ Lyra in Japan has 5 of these made by us. 3 of them with the SAT tonearm Good Listening Peter |
Lewm I have tried coper mats on the DP80 and the springs (thin metal bands) are not sturdy enough to carry the copper platters unless very thin. Any mat should be not any larger than the inner spring loaded platter - Denon's original Rubber mat supplied with the DP 80 is. I've uploaded a few pictures on my systems page showing the detail. https://systems.audiogon.com/systems/6431 Good Listening Peter |
Agree with Lewm, the DP80 is a fantastic machine. The rebuild of the electronic circuit is relatively simple, have done a dozen or more in the past year or so. Some time ago i posted a video showing the speed accuracy of the DP80 playing an entire LP side, 17minutes plus there are few tables that can perform in this class. https://www.facebook.com/170947997876/videos/10154978712417877/ https://www.facebook.com/170947997876/videos/10154978713202877/ The videos show a DP 80 fitted with a time line a device that emits a laser pulse at incredibly precise intervals projecting a dot on the wall in the room the table is in - in this video the wall the dot is projected on is 26 feet away from the table - over 17 minutes the dot moves forward with just a few inches - if theres any calculous geniuses out there try to calculate this accuracy in percentages it is WELL below specified accuracy.

I think your confusing the mater - the metal parts of the platter is dual coupled by leaf springs - the mat - the rubber thingy 🤣 has the label relief. The two metal platters are isolated by foam pads around their circumference by foam pads - 6 or 8 of them altered by rubber pads on the lower platter in designated pockets. The foam in all original ones are gone by now - there’s a suitable replacement available at Home Depot for $3 available - cut it into 0.875 lengths put it in place you will have 8 feet left. good Listening Peter |
chakster The bottom bearing "holding" plate comes off by removing 3 screws, so its pretty easy. I have added 3 photos on the Systems page for the DD tables. The last three ones https://systems.audiogon.com/systems/6431 Good Listening Peter |
I use Royal Purple Synthetic lubricant for lubrication of the bearings. https://www.royalpurple.com/product/synfilm-recip-100-reciprocating-air-compressor-oil/ Good Listening Peter |
