Hi again!,

Do somebody have the SEIKAKU DM 350W + 65W Schematics?. I am having some trouble with the switching PSU I think so.

There's a service manual for the Alto MS12 here:

http://forum.cxem.net/applications/core/interface/file/attachment.php?id=397542

It has the schematics and if IIRC, it uses the Seikaku module.

cyrano, thanks for the link and schematic, let me to check it bacause in first hand look like very similar but not the same....may be I can use it like guide!

The SEIKAKU DM 350W + 65W amp is the same for the Alto SXM112A (the mine unit!)

Thanks a lot again!

There probably are different generations of these Sekaku modules too.

I didn't know the brand, but a friend who designs speakers did. He told me these OEM units often get customised.
