Help to identify component

[RS232]

Hi all
Need urgent help to identify one component in a powered monitor for my local community center.
The part in question is marked 206B - J123B - JRC and is a smd opamp or so I thing.
The c. center needs it working for the Christmas party on the 25th so any help is welcome.

Most like NJM2068.

Could that "B" be an "8"? If so that may be a JRC2068 = NJM2068 = RS components #713-9824 in the UK

That is the same op amp used in the gain stage of the O2 headphone amplifier, just the DIP8 version:

Maybe you could tack solder an DIP-8 socket over the surface mount pads if someone nearby posts with a spare. The pinout is the same with the dip and smd versions.

Odds are probably good that the OPA2277 will work. At this late hour it might be a take-what-you-can-get situation.

sofaspud has a good point! The NE5532 would also substitute in a lot of situations. Same pinout:

Pretty much any dual opamp should go in there and the thing should work - BUT, you should be thinking about what fried it.

BUT, you should be thinking about what fried it.

And, even before that, whether it's actually fried. Why do you think it is?

Thank you all guys
What caused the failure was one of the guys from the band used one of the amplified outputs from the mixing table in to the line in socket.
This monitor is a piece of junk, the amp inside is actually a chip amp (TDA7294).
Well I got it working, I bypassed the amp and is now been used as a passive monitor till I get the parts from farnell.

Thanks and Merry Christmas to all
