anyone have a datasheet for a JRC 4005a op amp?

or know the makers website? i have a few suspicious opamps in a 2150sx i just picked up today.

someone put these in place of the ne5532's...im getting reverse polarity as i woud get from an 5532 on some of the legs.

couldnt find any info on these opamps, even on the makers site.

but i changed the opamps with TI ne5532's , first installing sockets....powered up and everthings good.

(the 5534's were still intact)

a couple of the drivers were bad too, but had one spare pair left.

this was the second 2150sx i picked up in one week!

thank god this was an easy fix...
