Still need help on mystery SanKen integrated circuit

[Don Lancaster]

Part number is SanKen SI-3150G Japan

Here us the image: http://www.tinaja.com/images/bargs/sankca01.jpg

It sure looks like a 20 watt stereo car audio output module.

Going to the "usual suspects" turns up SI3150's and SI3150F's and such
that are ordinary LDO regulators in wildly different packages.

What is this beast?
How old is it?
Where is a data sheet available?

On this page...

http://www.ecadata.de/suchneu/such.php?ECA_KEY=SI-3150G

it's called "Voltage Round About", which might imply multiple voltage
outputs ??

The site is in German. Perhaps Joerg can take a peek and decipher?

Thanks.

On taking the lid off, this really is a combination
rectifier/regulator/controller.

Probably ancient.

Appears to be everything for a power supply except the filter capacitor
and transformer. Almost certainly single output voltage.

Still need a useful data sheet.
The German site seems to link to "no data" pages.
