Opamp replacement: JRC 9003
Opamp replacement: JRC 9003
(OP)
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?

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...

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.

i had another look at the device and of course i was looking for the wrong code
Blinded by the obvious again
