Sony Schematics
I am looking for Schematics for a Sony Amplifier TA-313 from 1978-1979. If anyone could help?

Hi guys,

I have a problem with same sony amp. The chip (sanken - SI1125) is gone. I want to replace it with similar STK. Found STK4133, 4132II in store, but I don't know pin layout of the SI1125 and datasheet can't be found on the internet. I figure it out +in, -Vcc, +Vcc, Out, but chip has connection to extern tone controle circuit (bass, treble). How to connect STK to this?
Please if someone could give me some advice or post SI1125 datasheet.

Thanks very much in advance!!!

Maybe I should just use power supply, casing, VU metar, inputs... from the amp and put in LM3886 devices?

Hope someone will reply...
