Part number is SanKen SI-3150G Japan
Here us the image:
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...
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?

...Jim Thompson 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.
