The sound became more clear and sweet by reducing Bias by 3mv? No way my friend.
+1 A little fanciful I would say.

Precise setting of BIAS current is important for temperature stability of power stage and complete functioning of power stage... so there are no any kind of magic there.Since 3 mv is no big deal why Sansui instructions sets the decimal ????? for example, model 907 limited - 28.6 mV, models 907 .... 8,8 mV ....
you're right ! It's not magic! However, has its consequences in the sound ... I hear that colleagues and I agree with that - and you stick with theories ...

clear ... jomark suggest: set on the same channel nominal value and the second 3 mV more - OK? Be after what you hear OK? ............... Theories are not worth anything ...
setting a higher value than the face value causes thickening of sound and loss of detail, reduce the value of shallowing sound and more delicate.
The Sansui is important even a small value! especially within the factory! In models mos fet this effect is even more significant!
Also I was surprised at first.

Check for example Sony TA-F830ES, 4x 18.000uF Caps for Current amplifier and 2x 10.000uF for voltage amplifier. or Sony TA-N80ES, 4x 22.000uF for current amplifier and 6x 4.700uF for voltage amplifierAnyway I like this kind of design , and to be honest never seen it elsewhere
Well thanks for posting these. Japanese do have a problem with the English language so it is difficult for them to answer I suppose. I will try , since I need a couple of manuals .
Sansui AU alpha 907 limited and not only ....
You know the Tamura transformer alpha 907dr how many VA and '?
