| Vintage DD turntables. Are we living dangerously? "As I already stated my hope was based on Lew because he seems to like to mess with all kinds of TT's in his garage(?)."He sounds like my kind of guy! :) The inquisitive mind is a wonderful thing. _______ | |
| Vintage DD turntables. Are we living dangerously? There appears to be some confusions regarding Dual motors. Maybe I am the one who is confused... Let's answer each question one at a time. Nandric: "As I or 'we' (Lew included) thought there are at least twoDual motors: 701 and 721....... Lew sugg... | |

From my understanding of the Goldmund Studio situation is that...1) If you have nonworking motor, you need to replace it with...____A) Stock Papst motor, if you can find one.____B) Stock JVC motor, if you can find one. ____C) EDS-1000 motor salvag... | |
| Vintage DD turntables. Are we living dangerously? Wahwah: "However, no mention so far that Goldmund and Micro-Seikiused JVC core motors. Anyone care to elaborate on this?"From the few pictures I saw of the Goldmund and Micro-Seiki motors, they are not coreless motors. The motors are definitely ma... | |
| Vintage DD turntables. Are we living dangerously? Lewm, I was hoping you would click on the "Kenwood repairs (including three L-07D !!) prompt and click on any one of the L-07D buttons. (Obviously I am a finger clicking happy internet search fiend!) Check out all those dozens of hi-rez images of ... | |
| Vintage DD turntables. Are we living dangerously? Since the thread topic is about repairing turntables. I would like to share an amazing audio repair site that shows many hi-rez repair pictures. Totally audio porn for the gearheads like me. And I am sure of you already knew about this site.Amp8.c... | |
| Vintage DD turntables. Are we living dangerously? The topic about the Dual motor and later generation of coreless motors in L07D and Bardo has been covered by an Audiogon member who is also an aerospace engineer, Wjsamx in a thread about the Brinkmann Bardo from last year, as you might remember r... | |
| Vintage DD turntables. Are we living dangerously? The closest to the Dual 701 motor design is the later version of the Kenwood L07D motor because, like the Dual, it has two layers of coils except Kenwood made them in star shape to avoid patent infringement. Compare to the older version I think I ... | |
| Vintage DD turntables. Are we living dangerously? Lewm, I think the Bardo and L07D both took a page from the granddaddy of coreless motor, EDS-1000 from Dual 701.Brinkmann Bardo stator coilsKenwood L07D stator coilsDual 701 stator coilsLewm: "On Technics.

| Vintage DD turntables. Are we living dangerously? Oops, the posted image of the PS-X7 motor was supposed to be PS-X9, Sony's flagship. Sorry for the error. ______ | |
| Vintage DD turntables. Are we living dangerously? Lewm: "If you read about Kenwood's thinking in the design of the L07D, they actually did not favor high torque in principle. So they were not concerned with competing in that "horsepower" race."I think I agree with that thinking and from the sound... | |
| Vintage DD turntables. Are we living dangerously? Lewm: "The fact that Denon and Technics stuck with cored motors does not necessarily mean they were "stubborn"."Sorry, I did not mean to imply anything negative about Denon and Technics not using coreless motor. Perhaps the word "stubborn" was po... | |
| Vintage DD turntables. Are we living dangerously? My observation on coreless motors in direct drive turntables is that there are physical traits, at least the ones I owned and saw in pictures. Please keep in mind that I am not an motor engineer so my observation does not define what a coreless mo... | |
| Vintage DD turntables. Are we living dangerously? The TT-81 and TT-71 use the same CORE motor. The 81 uses more sophisticated electronic drive than the 71. Now, the TT-101 is a completely different beast. It uses a CORELESS motor and a "double bi-directional servo" in the electronics. So it is no... |
