Procedures and other data - start Procedures and other data - end The service manual (SM) for the Sansui AU-X11 has eluded my and everyone's (even boffins here in Japan) best efforts to locate.So I think that it is past time that an information collection point be created to accumulate any and all information about the model. I will be adding to this crowd sourced point of reference as I report voltage measurements on the X11 that I have that is properly functioning.And I will report on any information I find as I claw my way through Japanese AU-X11 restoration blogs. I will eke out as many new bits of information that is confirm-able in either pictures or second party testing. Standard disclaimer: All information in this thread is for reporting purposes only and is certainly not an official Sansui statement. Valid and test-able corrections welcome 10/22/2017 Addendum I will put all voltage adjustment procedures, and other information like that, here in the first entry of this thread. That way anyone needing that information will know exactly where to find it. Who wants to waste time digging through an entire thread for a test point voltage after all. ENTRY 1 Today's new tidbit comes from a Japanese restorer / blogger who calls himself Zyuou2015, and who's X11 restoration can be seen at https://blogs.yahoo.co.jp/zyuou2015/14843640.html . Among the very well photographed rundown of his X11 restoration we see this... ...the X11's Regulated Power Supply Circuit Board voltage measured at TP3 and TP4 are adjusted to 47.5V This is the same voltage for the same points as on the AU-X1. AND Let us not forget Nicowico's amazing report on Oct 25, 2015 that AU-X11 equalizer boards ( 2 of the 4 boards on the X11 phono motherboard) will also function as EQ boards in an AU-X1. http://audiokarma.org/forums/index.php?threads/the-mighty-au-x1.672322/page-6 Here is the X11 F-3452 EQ board . One of a pair. Here is the supplemental service bulletin which lays out the voltage adjustment procedure if you install the pair in an X1.
