G'day Folks . I hope you won't mind my pulling this one out of the Shorts Drawer again  :) If I might inquire of AD , I have been wondering , Re the AU-111 units upon which you have worked,  did you leave the original VR1 /VR2  in situ , replace same with a better quality pot (Not easy to...

Good Morning Folks . I would appreciate any opinion regarding a loony plan I have been mulling over . Whilst reading through the AU-111 manual I paid a little more attention to the various connection configurations open to the Au-111 owner and it would appear to me that I might be able to slave...

Thanks you for your considerations on this question A-D , this point , together with your recommendations on tweaking the performance of the AU-111 comprise some Valuable Research and Much Appreciated .   

Hey Eric , Yes Indeed , It was Isao's comments regarding global feedback that have kept me honest to the factory circuit . I was just wondering whether AD might have taken a look at that part of the circuit whilst evaluating some of the other component values on Moog's 111 and prompted my...

@AD ~ I am wondering , taking a look at the circuit and the way Sansui have the amplification stage set up do you feel that keeping the value of the coupling caps at 0.33uf is sacrosanct ? I have a few nice 0.47uf's 500v > 1200v at hand ie; Mundorf , Ampohm , VCap that might prove an...

Sound advice A-D ~ The power supply poly's are 1600V , 400V'ers on the HT of the Pre- and 630V/850V in the Output stage . I used the 250V Wima's only on secondary-sub circuit duties such as the various Function and Tone controls , nothing running to ground or handling more than a few Volts ~...

Yes I have to agree A-D , seem's odd practice ~ However the component layout appeared to be as factory untouched when I started the re-build of this first revision Black/Alu knobs serial No  96010372 . I have seen other builds along this configuration ~ I shall see what I can do to give the...

Staggered Over The Finishing Line In The End  !!! Stock Circuit ATM , No Mods ~ For Now  :)

Thank you for the qualification AD , re the 33nf , I had this correct in Version 1 then had doubts as the replacement for C90 is no longer tied to C1 hence V2 .

Hi Johan ~ I'm not sure that I have interpreted your changes in point 1 correctly , or have I ? 

Many Thanks for taking the time and trouble to list your experiences whilst servicing the Sansui Johan , Most Kind :0} My thanks also to Eric for greasing the wheels of communication . I shall enjoy digesting your recommendations and may well follow in your footsteps when my AU-111 service is...

Howdy Folks ~ Inaugural post here on this excellent forum  :) I find myself intrigued upon reading Ampdog's comments regarding NF and HF oscillation on the AU-111 and would be most grateful for a little further information on this point . All the best. TM
