[QUOTE="Ampdog, post: 563668, member: 144"] As some interest in the Sansui AU 111 has been rekindled by recent comments in the "For Sale" section on a restored model, perhaps some details. (This has in fact been posted before but I seem unable to access that thread. Perhaps PC memory also deteriorates with growing years ....) It was hinted that I 'improved' the circuit, which is true, but not dramatically so in audible sense. This was about a more logical choice of component values, but also some improvement in the power amplifiers. The latter had again to do with better balance and improvement of NFB stability rather than distinctly better sound. If of any interest I could expound on some of these for would-be restorers. May I in conclusion thank those members who there came forward with positive comments - I did follow the thread at the time. It is always gratifying to know that one's work is appreciated, even when hidden from normal view. Engineers also have their pride. [/QUOTE]
