[TV] Re: RCA COMPACT AUDIO SYSTEM MODEL RS2600

["John Conti" <contitv@xxxxxxxxxxx>]

Terry, the correct # is tda7269. this ic has its own standby and mute 
circuit built inside . when i removed pins 7 and 11 I got audio on my scope 
so I think I have a bad audio amp. anyway I order one and I'll let you know 
how it turned out.
thanks
john
