Opamp replacement: JRC 9003

[DonMartin]

I haven't been able to find a datasheet or even a pinout anywhere in the web. JRC hasn't responded so far either.

It supposedly is a dual opamp with single supply. It is from a Marantz amplifier.

Can aybody help?

I wonder if the "9003" is a date code (1990 March).

For the pin-out, assuming that the pin-count is reasonably low, can you examing the amplifer PCB to derive the IC's pin-out ? That's how I would start...

Also, look for the amplifier's schematic or service manual on-line somewhere. Such info might help with the IC.

There are many hits (audio related) for the following JRC opamps: NJM4556, NJM4560, NJM4565. Hopefully this lead (mostly the 'NJM' prefix) will help you to find the info you seek.

Ok guys,
i had another look at the device and of course i was looking for the wrong code - it is a NJM2041 Type. With that code i easily could find the datasheet.
Blinded by the obvious again ... thanks to all for setting me straight on this one.
