hmmm, I only see a 1.3K resistor...
Could you point out where the 1.3ohm one is?
If it's 1.3K, I'm sure it's not more than 1/2 a watt. |

| wooops i mean 1.3k |

another problem i made the schematics like in that picture i posted above and the problem is:amp is working but it sound like boo boo boo and another strage noises like radio.Input is good.Maybe you had problems like i have?
and more it sounds not slightly with interruption like someone is switching the power. |

| I realised this circuit (bridged TDA1514A) 3 years ago on a PCB. That 1.3K is a 1/4W standard resistor. I guess it determines the GAIN. I am not using this circuit now! Because I haven't got big driver... But it has very good sounding as I can remember.. |

I may be wrong, but it seems to me like the inverting and non-inverting inputs on the amps have been mixed up, at least in the schematics. Should make a funny oscillator, rather than an amplifier...

Yeah its true! As I can remember, I swapped the second amplifier's inv and non-inv pins (or the first...!) But if u get this circuit from the Philips's Audio Amplifier Book, it's absolutely a 100W oscillator...
Hmmm, if I'm not wrong, that circuit killed my 8" subwoofer, after that somebody said me "u must swap the pins".... But it was a long time ago.. And I am an old man.. (my intelligence age!). |

| so can anybody post how to make it work normaly?(circuit) |
