Due to financial situation, I was forced to sell all my SP10s. :( I still have some DD tables from various brands and a Lenco. Currently I do not have any belt-drive tables so I don't even qualify as an audiophile. :)

want new plinth ideas for direct-drive turntables
By now, the idler-drive genre has enough ink on them without me adding anything new to the topic. What is little talked about is the "guts" of direct-drive tables. Many vintage DD units suffered from bad plinth design with inadequate solidity (often mounted to crappy plastic or flimsy particle-board) and inadequate isolation from resonance and interference of electronics.
I like the bare bone approach, that is, to take the motor out of the chassis/plinth/enclosure and mount it to a something solid, material of your own choice, and extend the cable by at least couple feet to the stock chassis or an enclosure that contains the electronics/motor-drive/control-console/power-supply. In fact, the Monaco Grand-Prix, Teres Certus, or early Micro-Seiki DDX/DQX-1000 takes the same approach.
Almost ALL DD tables can be improved this way. There are many other brands of superb DD tables with great potential out there can be had for very reasonable price and can be converted this way with good result. I no longer have any Technics tables on hand to experiment but I still got great results with some mid-priced JVC, Pioneer, Kenwood, Yamaha, etc... I haven't tried it on Sony and Denon tables yet because they require mounted a tapehead to check platter speed so the mounting is tricky. Modern belt-drive turntables have been doing similar things by separating the motor from the main plinth. Once again, Micro-Seiki was ahead of their time with their RX-1500 and beyond. It's only logical DD will go that direction. The days of having everything in a box for DD tables seems less attractive to me now.
If you have other ideas, feel free to talk about it here. And hopefully this will generate more new interest in the DD genre. Personally I am more interested in people's experience with brands other than Technics as they already got enough coverage in other forums and threads. Nothing against Technics, just want to direct attention to other sleepers out there. Anyway, still feel free to share ideas.

Thanks for sharing. That's really nice work. You can see a rather poor photo of my slate Lenco in my system post here on Audiogon. Plinth is a monoblock of slate, unlike yours. Used Peter Reinder's top plate. Probably should post it in Lenco Heaven as well. I run it thru a Walker Audio Motor Controller, but I am in line to receive a Mark Kelly controller specifically designed for the Lenco motor. |
Thanks for sharing, Borning50. Speaking of Pioneer, here's a PL-30L that got an overhaul by a Japanese audiophile that's pertinent to my idea. The motor is very similar (probably the same) to the one in my PL-L1000 linear tracking table. Since the bottom of the motor is flat, you don't even need to cut a big hole on the plinth. A great candidate for such mod. Check out the links to other cool stuff, including a linear tracking arm using motion control glides from THK. Very cool. http://kiirojbl.exblog.jp/i108 http://kiirojbl.exblog.jp/i109 ____ |
Great photos on that site, thanks for the link. The 518 project is not mine, although I do have a footless 518 waiting for surgery! :) Lewm, I think it would be a good idea to post your Lenco project at LencoHeaven, and there is a thread on motor controllers where your thoughts would be welcome too. :) |
