Hi all!

I'm building an amplifier based on the TDA7294 chip and have had a look at some different schematics. One thing puzzles me a bit (on attached schematic) the C8 lytic has positive side to gnd. However on other schematics it is the other way around (with nothing else changed). Can it be both ways or what is the correct orientation of the cap?

Thanks

As far as I know, the C8 cap's polarity is reversed in your schematic :usd:. Please look at the datasheet from ST and zoom in the PDF file in order to see that cap. You'll notice the right polarity as given by the manufacturer.
