Nude Turntable Project

Lewm: "Where are the electronics? Show us what is at the other end of those wires coming off the bottom of the motor. Thx."

Here's a picture of the DP80 from bottom view of the gut. As shown, the motor has only three wires with a three-pin connector to connection "CN3" on one of the circuit boards.

Here are more pictures from the invaluable Japanese website Amp8.com

This approach of removing the raw motor from stock chassis to custom plinth has been done before, especially on the Technics SP-10Mk2 by Kaneta:

P.S. One more thing about Denon or Sony direct drive turntables is that there's a tapehead to read the magnetic print on the platter inner-rim for the speed servo system so besides the motor wires needs to be rerouted and extended back to the stock chassis, the wire for the tapehead need that as well. I believe in the western world, the Mitch Cotter turntable uses the same concept using either a Technics or Denon DD table as the basis for the mod.

Lewm: " I don't quite know how Steve managed to separate motor from chassis; it's not obvious from external inspection how that could be achieved without some cutting."

Here are many innards pictures of the Technics SP-10MK3 from Amp8.com. Just click on any one of the links to see repair and gut pictures of each unit.

Hiho, I have been inside my own Mk3, so I have seen those sights. I looked at a few of the URLs you provided and don't yet see how the Mk3 motor can be parted from the company of its chassis, but perhaps the info is there somewhere. I guarantee I will never do it. Doing it for the DP80 promises greater rewards, because there we do have the issue of a hollow space under and around the motor housing. But re-establishing the tape head reading system is a ticklish business, I would think. I did add damping to the underside of my DP80 chassis, in the form of beeswax melted out from an old KLH9 ESL power supply. There was a definite audible improvement.

I have also seen those websites and deeply regretted that I cannot read Japanese. My son could easily translate, but he hates for me to ask such favors and would therefore take forever to do it. Do you read Japanese?

Lewm: "I looked at a few of the URLs you provided and don't yet see how the Mk3 motor can be parted from the company of its chassis, but perhaps the info is there somewhere."

Here are couple pictures showing the SP10Mk3 motor wires can be detached from the connector next to the motor, whereas in SP10Mk2 the wires exit out of the motor and routed to the PCB.

I agree. The DP80 holds great promise and you might like it even more after "replinthing" it. Yes, re-establishing the tapehead position will be tricky but not impossible. I have few Sony PS-8975 tables that I am tempted to try a new plinth but the tapehead issue is discouraging me so I moved on to other DD turntables for experiment...

Lewm: "Do you read Japanese?"

I can read Chinese but not Japanese. There are some Chinese characters, Kanji, that I can decipher but it's hard to understand in proper context. I just use Google Translate.
