Thanks to the diligent efforts of Alan Turner, I am happy to present to the public the following files. They include three .pdf files (Adobe Acrobat) and three .jpg files of the tubing layout in the "Half" Duo-Art player mechanism. Clicking on the thumbnail images below will open the full size images. You can save the large .jpg pictures to your computer by Right Clicking on the image and selecting the option 'Save Image As' or 'Save Picture As'. I have also created Zip (.zip) files that can be saved by clicking on the text. Needless to say, I am grateful to Alan for sharing these diagrams with me, and I hope that others will find them very useful.
Also, if you follow this link (click here), you will see photographs of the system that's installed in Hans J. Schweizer's 'Half' Duo-Art. He has made one or two small changes to suit his own desires, but the placement of the various components appear to be the same as in the system that I looked at some years ago. Lastly, if you follow this link (click here), you will see the photos that I took while dismantling the upper section of a half Duo-Art. The pictures show, quite clearly, how the tubing was routed from the trackerbar to all of the other components attached to the upper section of the mechanism. The pictures are presented in the order in which they were taken; from before I started taking things apart until the final component was removed. Last, but not least, you can follow this link (click here) to a written explanation and diagrams sent to me by Rollie Chisnell. I've taken the liberty of cleaning up the text and graphics, and present them in two formats (.wpd/Word Perfect and .pdf/Adobe Acrobat).
Finally, it's my feeling that when all of this information is taken as a whole there is very little left to say about how the Half Duo-Art is tubed. However, with regards to how each of the devices within the system function internally, I refer you to the last and final page in this series (click here). At this location you will find scanned pages from the Duo-Art Service Manual. They have been at Player-Care for a number of years, just waiting for a situation like this to arrive, and I'm glad I finally found a good use for them. Naturally, if you have any questions regarding any of the information, you can always write to me via my secure email form (click here) and I'll be happy to render any assistance I can. If all goes according to plan, there will be one more page that has a list of links to pertinent articles in the Archives at the Mechanical Music Digest. It is at this site that I began my quest for the knowledge contained in all of the pages mentioned above. Signed: John A Tuttle
