first, i want to excuse for my english, 'cause i don't use it very much:)
i have amplifier circuit schematic which uses TDA2030 as a driver stage for a pair of power transistors (BD249/250)
cause TDA2030 has worse PSRR than LM1875, and they otherwise look alike, i think to use National's chip
anybody can see a problem with that?
P.S. currently i can't give the schematic, but if you need it i'll find a way to scan it. |

Hello!
I think that there is no problem!
Values of resistors in feedback are same as LM1875..
I replace power board of an old Cambridge Amp and LM1875 sound really good...
Have a nice day..

Yes,
It is better by all parameters. Even sound better & more output.
