Sanyo/B&O Icepower 200AC Rev.D, schematic about rev. engin., not complete finished
 
some time ago I had make trobleshooting and repair by a ICEPOWER module from B&O. Therefore I must create a schematic, that was not available by the manufacturer. But the schematic was difficult to reconstuct, because the PCB use multilayer technology. So any connections are not to see and some other are unknown, where do they go (at whole four or five wires - I think).

Nevertheless this schematic could be of interest for one or the other.

Perhaps one of the members this can complete.

this topology could be also interest for diy, because no special made IC's respective custom made semiconductors are inside - in opposite to the most other brands.

Because some guy's claim, the best topology ever made without special made resp. custom made IC's (I want to know, how - there are a big story behind this topology - you will find with the keyword "ICEPOWER", "B&O" and "Sanyo" so as some names of the developer's).
for some examples go to

And for fault finding by such modules, some year ago.

Do you know, where I can buy this modules as industry part and not as replacement part?

No idea, where I get this modules?

Here a basic AES article:

Only directly from ICEpower.

Hmm, I tried once contacting them using this address: ICEpowerinfo@bang-olufsen.dk - no answer until now. There is also a phone but this may be an expensive international call. Do they sell single units to private persons? I need ASX2 module but I'm not a manufacturer. I just need to replace non-working module in an amp.

Unless they've changed their policies then no. You need the manufacturer of the end product to replace the damaged module.

I thought so. That's bad because I live in Europe and the amp is from the States. Sending the amp to the States and back would cost a fortune.
I would be nice I they'd at least answer to emails (even if they cannot help), or if they provide some kind of a service (for non-manufacturers) in Europe.
