Hi, does anyone have a datasheet for this chip? I would also like to know if it's a fake or an original, below the photo.

you can replace with a stronger STK 407-090 e.g.

But this is the Original, and the note from a colleague of Radiogag is only a list of systems.

I am thinking of developing an amplifier out of it, so I am looking for a datasheet

There is no datasheet on the internet. I was looking for this type of note myself. A colleague is saved by the scheme of the device in which the bones from this STK family worked. For example, from the Sony RX90 tower.

I found something like this, but I don't know if I can apply:

No, this is not a sure pattern.

Added after 18 [minutes]: PS-STK407-070 Vcc min +-29V Vcc max +-45V Pout max 2x70W -R-6om Rin-50kom

here is part of the pioneer xc21 block with the stk chip ....

I am just fixing it, so when looking for a diagram, I thought that I would throw it and it would be useful Added after 2 [minutes]: sorry something went wrong here is the link

From what I found, 070 is not interchangeable with 090 Examine the schematic of pioneer and the second stk407-090 application Added after 4 [minutes]: I add full service and STK407-70 applications from what I found out 090 seems to be stronger but different pinology of the system. I do not propose to replace it.

Where can I find a datasheet for the STK407-070, and is the chip in the photo genuine or fake?

A datasheet for STK407-070B was linked, but the thread also says there is no exact STK407-070 datasheet available online, so the recommended approach is to use the schematic/application diagrams from equipment that used this STK family instead [#13043058] [#13044035] [#13048231] One reply explicitly said the chip in the photo is the original [#13043996] A later post shared a Pioneer service-manual page and STK407-70 application information, but another user warned that STK407-070 and STK407-090 are not interchangeable because the pinout differs [#18625944] [#18626492]
