I wonder if the Yamamoto Hydraulic Arm Lift could be easily fitted to the Amadeus for those of us who may be a bit shakier than others. -Bob Scroll to the bottom of the page: http://www.jacmusic.com/Yamamoto/html/Phono/index.html |
Hi Ghunter, I'm kind of thinking about getting a WTA (and also kind of thinking I really shouldn't spend that much). My concern is that my hand just isn't steady enough to handle the arm safely. I've seen the video demonstration on the Amadeus blog and tried the same method on my current arm. Scraaaaatch! I'm not really THAT old and shaky (yet), but I ain't quite as steady as I used to be, either! -Bob |
Hi Sam, No, I don't have an Amadeus, so I am not trying to tell you what you should do. But I am really curious about the turntable and am trying to learn more about its tonearm/cartridge geometry. I guess I really don't understand your question. As far as I can tell from reading the Amadeus blog and the owner's manual, you're just supposed mount the cartridge in the fixed headshell and be done with it. It seems to be impossible to adjust the overhang or the tracking angle. I don't understand what you mean by, "the nude point of the protractor is 1 7/8 inches." What exactly is your question? On the Amadeus blog, it states: "After my investigations, I decided to relieve users of Amadeus of the issue of setting tonearm geometry and to use a fixed geometry. Based on the comprehensive analysis of J.K. Stevenson in the May and June 1966 article Pickup Arm Design and based on the dimensions of several phono cartridges in my inventory, I designed the tonearm for Amadeus to have a fixed tracking angle of 19 degrees and an overhang of 0.5." ...and... "The Amadeus Headshell is factory fixed in position. The Well Tempered Lab unequivocally reiterate that it should not be moved." The owner's manual states: "The headshell is fixed ex-factory in the optimum position. There is no provision for over-hang adjustment." This seems to imply that all cartridges in Mr. Firebaugh's inventory produce an overhang of 0.5" when mounted on the fixed headshell of the Amadeus. That means every cartridge he has must have the same distance between the cartridge's mounting holes and the tip of the stylus. Given the wide range of this dimension that I've found among cartridges in my experience, this is difficult to believe. Perhaps it would be helpful if Mr. Firebaugh told us which particular cartridges produce an overhang of 0.5" when mounted on the Amadeus?? -Bob |
Chashas1, I'm still kind of struggling to understand various comments about the Amadeus. If the headshell is fixed in position, how is it possible to "set the cartridge parallel to the lines"? This would imply you can alter the position of the cartridge in the headshell (i.e., by at least twisting it). But how is this possible if the headshell is fixed in position? Thanks for any help you can offer. -Bob |
Thanks, Chashas1. So if I understand you correctly, you CAN adjust the tracking angle simply by virtue of the "play" afforded by the cartridge-mounting screws in the headshell mounting holes, correct? (BTW, by "twisting" in my above post, I was referring to twisting the cartridge, not the headshell, which I know is fixed in position.) Is there also enough "play" to achieve the optimum overhang of 0.5"? It seems this would be difficult to do, considering the widely varying lateral distances between the mounting holes and the styli of various cartridges. These issues are not addressed in either the WTA blog or the user manual, as far as I can tell. Thanks again, -Bob |
Tbg, I don't know what "the option" is that Samtse mentioned, but I'm wondering whether you saw this link I posted earlier in the thread to an add-on tonearm cueing device from Yamamoto: http://www.jacmusic.com/Yamamoto/html/Phono/index.html Scroll down to the last item on the page. Not sure it's size would be exactly right for the Amadeus, but it might be. -Bob |
