fedeleluigi Posted February 7, 2017 Report Share Posted February 7, 2017 Here is the AR 10 Pi schematic coming from a copy of an AR original drawing sheet. Unfortunately the copy I have is not complete and a part of the AR drawing sheet is missing. I couldn't find this schematic in the "AR Drawings" section, so I hope it can be added to the other files somewhere in the Library in order to allow everybody to see it. I think it's a rather rare document even though, unfortunately, not complete. I have scanned it as TIFF format then I've converted it to JPEG to insert it directly into this post. To get a higher resolution, save the attached file in Tiff format. Differently from LST, in the AR 10 Pi the auto-transformer and the 3 dB step switches permitted the listener to have more flexibility with a total of 27 different combinations of driver output level (that is 27 different frequency responses) without using any attenuation resistor. The auto-transformer enabled the user to control bass output by a 3 step switch as well. Luigi AR10 Pi original schematic TIFF.tif Link to comment Share on other sites More sharing options...
