Nando,

If in Brazil, you know better than me. But in the States many places.
Here's one one
Try Google and you will find them. Hope that help.

P.S. Regarding the design. I have a STK428-640 datasheet from Sanyo in Japanese. There's some kind design (circuit) in it, but as we know there are million of odds and ends in this hobby. I am not comfortable with wiring up a design with the rest of instructional text in another language.
 
Could you also send this datasheet to me?

Well, I also have the Japanese version, and the schematic only have the name of the parts, like "C10", "R14"... No values, and everything is in japanese :cannotbe:

This module might be VERY good, it's carrier frequency is pretty high, and as I could read in the product brief (english), it have focus on quality.

I'd love to get one of these chips and have the full datasheet. ;)

Did you buy from this site that you sent the link?
 
Hi nando, I've sent you an email giving you my contact email at work. Drop me a private email and I'll send you the datasheet.

The amps are high quality (ICEpower), but I was looking at using them to drive step-up transformers for 100V-line PA applications, and like most pre-filter feedback amps, they don't like a load that can change a lot. (100V amps have to cope with wildly verying loads depending on the number and power-tappings of the speakers attached).
 
Could you please send me a copy of STK428-430's datasheet as well. Thank you.
I took a closer look at the Japanese datasheet. Apparently, they're intended for 2-way speaker system. Dual-channel, with one channel's response 20-20KHz 150W 0.8% THD into 8 Ohm and the other's response 1KHz 200W 10% THD into 4 Ohms. These specs are way downgraded compared to B&O's standard ICE modules. It could be the COM & MECC can not be fully implemented on the same die/wafer ? (I wonder)
