Hi,
Thanks very much for the fast reply, But it's none of the ones you mentioned.
As to a photo it is only a "standard 8 pin surface mount Op Amp in a Bose Car Amplifier
These Op Amps are used as low pass audio filters for the 6 outputs of a Crystal Semiconductor CS4226 DSP processor

Hi
the C934 is very hard to find.
On the datasheet of DSP CS4226 suggest to use as amp-op
the MC34074 or MC33078

I sincerely think that the c934s can be replaced with many equivalent amp-op.
On pcb it is easy to see Supply Pin and I/O pin of old C934
(I think that this is a dual standard SMD amp-op)
