anTiTon ARNO Hybridverstärker

[Rainer]

Hello Paulo, 

last weekend I spent a long time gathering information about the LM1875 chip from National semiconductor. Analogue poweramp chips are new territory for me. 

Without letting this thread get technical, I would like to know whether you considered using the Sanken SK18752 during development? There seem to be quite a few who prefer it. But it's a mysterious chip. 

Apparently it is a Sanken "tuned" LM1875 with identical circuitry. +/-33V DC as optimum. There is no data sheet and the only short-term commercial use was limited to Japan in individual Sony and Denon amplifiers. There are still stocks of the original ones to this day.



Apologies for technical question removed from the purely audiophile treatment of the Arno here.

Best Regards,
Rainer
