Found a Power amp "STK4133ii"

[Tsili]

So, I found a power amp, specifically this one:
STK4133II WITH BOARD - Integrated Circuit - KSP ELECTRONICS
(Yes, with the board)
I searched the web but didn't found any datasheet that explaines what are those 18 pins do or even better, where shall i connect the 9 coloured cables of this board.


Does anyone have any clue?

I saw this but It's in German (I suppose).

Besides from the different language It doesn't even have the information I need.
At how many volts this amp functions? How many watts output does it have?
From the small research I did, I understood that this datasheet only describes how to replace a power amp from old sony devices.
Correct me if I am wrong.

Edit... just realised this is showing the STK4132, not the 4133

Look here:
STK4132II datasheet(1/8 Pages) SANYO | 2ch AF Power Amplifier (Split Power Supply) 20W + 20 W, THD =1%

20 watt and -/+23 volt recommended supply.

And Donberg say it is a voltage regulator... there were some STK voltage regs that used to be used in VCR's many years ago but I can't recall the number.

I am not sure but I will assume that Donberg is wrong. Thanks for the Info!!!

This item is totally obsolete and the only information would be to trawl the interweb for a Sony product that uses one and get the values from there.

I remember STK voltage regulators from VCR's And they did
not have that many pins, maybe 12.
See example.

Im pretty sure its a power amp. It was a spare part my father had that he didn't want anymore as repairing such devices isn't the case the last decade.

I think so too.

That's the one, and I seem to recall a STK5482 as well. A long time ago
