Sansui AU-9900 & AU-11000 Differences

Hello,
Between the two, are there any major differences, not defined in the SM? I see only minor ones, specific to power transformers, some resistor values on the F-2630 PS board and probably some cap and resistor values on the "common parts list". Driver board and power transistors, as shown, are identical. Is that correct, or am I missing something in the SM? Reason for asking, is that I already have an AU-9900, but may have the option to pickup an AU-11000 shortly. Thanks in advance for any input.

I think that this has been asked in the last year, but I don’t remember the answer. I believe that it was mostly just the rated output.
They do share a SM FWIW.
 
Thanks. Yes 80 Vs 110 w. Would have expected some more differences. Anyways, if I do pick it up, I can compare the actual boards, providing the AU-11000 has not been tampered with.
 
The common service manual tells you everything you need to know as far as similarities and differences. My take is the only differences are those needed to get the higher wattage rating for the 11000. I would expect to hear zero differences in the sound between the 9900 and 11000. Unlike other Sansui equipment that share a SM like the 9090/8080 and QRX9001/8001 (among others), the 9900 and 11000 don't even have any functional differences. The face plate and controls are identical (other than the number stamped on the front.)

If it were me, I'd spend my audio $$ on something different from what I already had.
 
I have the 11000A, it is a great looking and sounding amp, and I believe that other than the volume control it is very much the same as the non-A.
 
KiethD/SaturationPt,
Thank you for the replies. I think I will proceed with the acquisition, providing it is still available, when I travel that way. Would not plan on keeping both. I picked up my AU-9900 last year, and after some help from AK members, you included, if I recall correctly, had it up and running. Very impressed, with the modular design and (somewhat) easy access, for testing and component replacement, with this Sansui series. If the AU-11000 tests as well as my AU-9900, then it will be a keeper. I think I can find a new and loving home, for the AU-9900, rather quickly.
